Schiff Base Reaction Products of Aldehydes and Alkyl Anthranilates and Organoleptic Uses Thereof

Our invention relates to novel reaction products which are schiff bases of aldehydes and alkyl anthranilates and organoleptic uses thereof in augmenting or enhancing the aroma or taste of perfume compositions, colognes, perfumed articles, foodstuffs, chewing gums and beverages.

Inexpensive chemical compositions of matter which can provide lemony, floral, green, ozoney, fruity, melony, citrus, piney, grape-like, woody, sweet and muguet aromas with anisic, fresh cut wood, ozoney, fresh air, floral and orange flower topnotes and anisic, woody, floral, green and citrus undertones are highly desirable in the art of perfumery. Many of the natural materials which provide such fragrances and contribute desired nuances to perfumery compositions as well as perfumed articles including solid or liquid anionic, cationic, nonionic or zwitterionic detergents, fabric softener compositions and fabric softener articles are high in cost, vary in quality from one batch to another and/or are generally subject to the usual variations of natural products.

By the same token, materials which can provide intense grape-like aromas and tastes are highly useful and are well known in the art of flavoring for foodstuffs, toothpastes, chewing gums, medicinal products and chewing tobaccos. Many of the natural materials which provide such flavor nuances and contribute desired nuances to flavoring compositions are high in cost, vary in quality from one batch to another and/or are generally subject to the usual variations of natural products.

There is, accordingly, a continuing effort to find synthetic materials which will replace, enhance or augment the essential flavor and fragrance notes provided by natural essential oils or compositions thereof. Unfortunately, many of the synthetic materials either have the desired nuances only to a relatively small degree or else contribute undesirable or unwanted odor to the compositions. The search for materials which provide, for example, a more refined grape-like flavor or more refined lemon flavor, for example, has been difficult and relatively costly in the areas of both natural products and synthetic products. By the same token, the search for materials which can provide a more refined lemony, floral, green, ozoney, fruity, melony, citrus, piney, grape-like, woody, sweet and muguet aroma, for example, has been difficult and relatively costly in the areas of both natural products and synthetic products.

Artificial flavoring agents for foodstuffs have received increasing attention for many years. For many years such food flavoring agents have been preferred over natural flavoring agents at least in part due to their diminished costs and their reproducible flavor qualities. For example, natural food flavoring agents such as extracts, concentrates and the like are often subject to wide variations due to changes in quality and type and treatment of the raw materials. Such variations can be reflected in the end products and result in unfavorable flavor characteristics in the end product. Additionally, the presence of the natural product in the ultimate food may be undesirable because of increasing tendency to spoil. This is particularly troublesome in food and food uses where such products as dips, soups, chips, sausages, gravies and desserts and the like are apt to be stored prior to use.

Even more desirable are products that can serve to substitute for difficult-to-obtain natural perfumery oils and, at the same time, substitute for natural flavoring ingredients in foodstuffs, chewing gums, medicinal products, toothpastes and chewing tobaccos.

Reaction products of carbonyl-containing compounds and amine-containing compounds are well known in the art of flavoring and in the art of of perfumery. Thus, U.S. Pat. No. 4,618,501 issued on Oct. 21, 1986 discloses the flavoring of foodstuffs with alpha,beta-keto-amines and states that an alpha,beta-keto-amine having a nutty corn, cereal aroma may be used for flavoring compositions for foods having the structure: ##STR10## wherein R.sub.1, R.sub.2 and R.sub.3 are selected from the group consisting of a saturated or unsaturated alkyl straight or branched chain hydrocarbons having from 1-3 carbon atoms.

U.S. Pat. No. 3,625,710 issued on Dec. 7, 1971 discloses the use of aldimines as chocolate-like flavors which aldimines are resulting from the reaction product of amines and aldehydes, for example, N-isobutylidenefurfurylamine, N-isopentylidenefurfurylamine, N-isopentylideneisopentylamine.

Schiff bases are also well known in the art of perfumery. Thus, for example, Chemical Abstracts Volume 103, 1985, No. 123134z (Abstract of Japan Kokai No. 60/78951 discloses the use in perfumery of compounds having the structure: ##STR11##

The book "Flavor & Fragrance Materials-1987" published by Allured Publishing Corporation, P. O. Box 318, Wheaton, Ill. 60189-0318 discloses on page 154 the commercial availability of the following schiff bases:

Methyl anthranilate and amyl cinnamic aldehyde;

Methyl anthranilate and hydroxy citronellal;

Methyl anthranilate and lilial;

Methyl anthranilate and anisic aldehyde;

Methyl anthranilate and decanal;

Methyl anthranilate and lyral;

Methyl anthranilate and iso-nonylaldehyde;

Methyl anthranilate and phenylacetaldehyde;

Schiff bases are also known to be useful as intermediates in producing other fragrance materials. Thus, U.S. Pat. No. 3,898,283 issued on Aug. 5, 1975 discloses novel schiff base intermediates used in producing 4 or 5 phenylpentenals having the structure: ##STR12## wherein X is a moiety selected from the group consisting of: ##STR13## and wherein R.sub.a is hydrogen or methyl.

Referring to FIG. 19, FIG. 19 is a schematic cut-away elevation diagram of the extrusion and pelletizing apparatus useful in carrying out a process for incorporation of the schiff bases of our invention into polymers during the operation of said apparatus. Motor 15 drives the extruder screws located at 23A in barrel 16, the extruder being operated at temperatures in the range of about 150.degree. up to about 250.degree. C. At the beginning of the barrel resin at source 12 together with additives, e.g., opacifiers, processing aids, colors, pearlescent agents and densifiers at location 13 is added via addition funnel 14 into the extruder. Simultaneously (when the operation reaches "steady state", one or more of the schiff bases of our invention is added to the extruder at one, two or more of barrel segments 3-8 of the extruder (which may be a twin screw or single screw extruder) at locations 18a, 18b, 18c and 18d by means of gear pump 23 from source 17. From source 19 into barrel segments 5-10, the gaseous or liquid blowing agents, e.g., nitrogen, carbon dioxide and the like are added simultaneously with the addition of the schiff base of our invention. The feed rate range of the resin is about 80-300 pounds per hour. The feed rate range of the schiff base taken alone or further together with other perfumant is between 1 and 45% of the feed rate range of the resin. The blowing agent rate range is such that the pressure of the gas or the pressure over the liquid being fed into the extruder is between about 50 and 200 psig. If desired, the extruded ribbon or cylinder may be passed through water bath 20 and pelletizer 21 into collection apparatus 21a.

Referring to FIGS. 20 and 21, there is provided a process for forming scented polymer pellets (wherein the polymer may be thermoplastic polymers such as low density polyethylene or polypropylene or copolymers of ethylene and vinyl acetate or mixtures of polymers and copolymers such as copolymers of ethylene and vinyl acetate and polyethylene) such as pellets useful in the formation of plastic particles useful in fabricating cetain articles which may be perfumed. This process comprises heating the polymer or mixture of polymers to the melting point of said polymer or mixture of polymers, e.g., 250.degree. C. in the case of low density polyethylene. The lower most portion of the container is maintained at a slightly lower temperature and the material in the container is taken off at such location for delivery through the conduit. Thus, referring to FIGS. 20 and 21, in particular, the apparatus used in producing such elements comprises a device for forming the polymer containing perfume, e.g., polyethylene or polyethylene-polyvinyl acetate or mixtures of same or polypropylene, which comprises a vat or container 212 into which the polymer taken along or in admixture with other copolymer and the perfuming substance which is at least one of the schiff bases of our invention or mixtures of schiff bases and other compatible perfumes is placed. The container is closed by means of an air-tight lid 228 and clamped to the container by bolts 265. A stirrer 273 traverses the lid or cover 228 in an air-tight manner and is rotatable in a suitable manner. A surrounding cylinder 212A having heating coils which are supplied with electric current through cable 214 from a rheostat or control 216 is operated to maintain the temperature inside the container 212 such that the polymer in the container will be maintained in the molten or liquid state. It has been found advantageous to employ polymers at such a temperature that the viscosity will be in the range of 90-100 sayboldt seconds. The heater 218 is operated to maintain the upper portion of the container 212 within a temperature range of, for example, 220.degree.-270.degree. C. in the case of low density polyethylene. The bottom portion of the container 212 is heated by means of heating coils 212A regulated through the control 220 connected thereto through a connecting wire 222 to maintain the lower portion of the container 212 within a temperature range of 220.degree.- 270.degree. C.

Thus, the polymer or mixture of polymers added to the container 212 is heated from 10-12 hours, whereafter the perfume composition or perfume material which contains one or more of the schiff bases of our invention is quickly added to the melt. Generally, about 10-45 percent by weight of the resulting mixture of the perfumery substance is added to the polymer.

After the perfume material containing the schiff base of our invention is added to the container 212 the mixture is stirred for a few minutes, for example, 5-15 minutes and maintained within the temperature ranges indicated previously by the heating coil 212A. The controls 216 and 220 are connected through cables 224 and 226 to a suitable supply of electric current for supplying the power for heating purposes.

Thereafter, the valve "V" is opened permitting the mass to flow outwardly through conduit 232 having a multiplicity of orifices 234 adjacent to the lower side thereof. The outer end of the conduit 232 is closed so that the liquid polymer in intimate admixture with one or more of the schiff bases of our invention or mixture of perfume substance and one or more of the schiff bases of our invention, will continuously drop through the orifices 234 downwardly from the conduit 232. During this time, the temperature of the polymer intimately admixed with the perfumery substance in the container 212 is accurately controlled so that a temperature in the range of from about 240.degree.-250.degree. C., for example, (in the case of low density polyethylene) will exist in the conduit 232. The regulation of the temperature through the controls 216 and 220 is essential in order to insure temperature balance to provide for the continuous dropping or dripping of molten polymer intimately admixed with the perfume substance which is all or which contains one or more of the schiff bases of our invention, through the orifices 234 at a rate which will insure the formation of droplets 236 which will fall downwardly onto a moving conveyor belt 238 caused to run between conveyor wheels 240 and 242 beneath the conduit 232.

When the droplets 236 fall onto the conveyor 238, they form pellets 244 which harden almost instantaneously and fall off the end of the conveyor 238 into a container 250 which is advantageously filled with water or some other suitable cooling liquid to insure the rapid cooling of each of the pellets 244. The pellets 244 are then collected from the container 250 and utilized for the formation of other functional products, e.g., garbage bags and the like.

FIG. 22 is the GLC profile for the crude reaction product of Example VIII. (Conditions: 50 m.times.0.32 mm OV-1 column, programmed at 60.degree.-220.degree. C. at 4.degree. C. per minute).

FIG. 25 is the GLC profile for the crude reaction product of Example IX. (Conditions: 2'.times.0.125" 5% SE-30 column programmed at 230.degree. C. isothermal). The peak indicated by reference numeral 2501 is the peak for the compound having the structure: ##STR66##

Our invention provides schiff base compounds and compositions of matter produced by means of the reaction of alkyl anthranilates having the structure: ##STR67## wherein R.sub.3 is methyl or ethyl, for example, methyl anthranilate having the structure: ##STR68## with aldehydes having the structure: ##STR69## or mixtures of aldehydes having the structures: ##STR70## wherein R, R.sub.1 and R.sub.2 represent alkaryl, aralkyl, alkadienyl, hydroxyalkyl, alkenylcycloalkyl, hydroxyalkyl cycloalkenyl and alkoxyaralkyl.

More specifically, the novel compounds of our invention are produced by reaction of alkyl anthranilates having the structure: ##STR71## with aldehydes having the structure: ##STR72## wherein such aldehydes have the structures: ##STR73##

Furthermore, the mixtures of aldehydes having the structures: ##STR74## include the compound having the structure: ##STR75## as specified, supra, taken further together with at least one of the following aldehydes having the following structures:

(i) the compound having the structure: ##STR76## (hydroxy citronellal); (ii) the compound having the structure: ##STR77## ("lilial"); and (iii) the mixture of compounds having the structures: ##STR78## and ##STR79##

The reaction products of our invention are collectively termed "schiff bases"; but not all of the products produced according to the "schiff base" reaction set forth, supra, and specifically set forth, infra, contain the moiety: ##STR80## Thus, as will be seen, infra, the reaction of the compound having the structure: ##STR81## (also denoted herein as "Bergamal") with the compound having the structure: ##STR82## yields a small amount of the compound having the structure: ##STR83## and larger amounts of the compounds having the structures: ##STR84##

The resulting schiff bases of our invention produced according to the process of our invention are capable of augmenting or enhancing grape aromas and tastes of foodstuffs, chewing gums, toothpastes, medicinal products and chewing tobaccos.

The schiff bases of our invention as well as mixtures thereof produced according to the process of our invention are also capable of modifying or enhancing the aroma characteristics of perfume compositions, colognes and perfumed articles (including soaps, anionic, cationic, nonionic or zwitterionic detergents, fabric softener compositions, optical brightener compositions and drier-added fabric softener articles) and perfumed polymers by imparting thereto intense lemony, floral, green, ozoney, fruity, melony, citrus, piney, grape-like, woody, sweet and muguet aromas with anisic, fresh cut wood, ozoney, fresh air, floral and orange flower topnotes as well as anisic, woody, floral, green and citrus undertones, thus fulfilling a need in the field of perfumery and detergent and cosmetics manufacture.

The schiff bases of our invention are also capable of deodorizing detergent powders suitable for use in the washing of fabrics as well as detergent powders as well as hand soaps. Such detergent powders include bleaching compositions, for example, bleaching compositions comprising a peroxy bleach compound. The schiff bases of our invention have deodorancy as measured by having a Lipoxidase-inhibiting capacity of at least 50% and a Raoult Variance ratio of at least 1.1 and a malodour reduction value of between about 0.25 up to 3.0 as measured by the malodour reduction value test disclosed in U.S. Pat. No. 4,663,068 the specification for which is incorporated by reference herein; and in addition, a deodorant value of from 0.50 up to 3.5 as measured by the deodorant value test disclosed in U.S. Pat. No. 4,304,679 the specification for which is incorporated by reference herein.

The reaction to form the schiff base between the aldehyde having the structure: ##STR85## or the mixture of aldehydes having the structures: ##STR86## wherein R.sub.1, R.sub.2 and R are defined, supra, and the alkyl anthranilate having the structure: ##STR87## wherein R.sub.3 is methyl or ethyl are as follows: (i) the temperature of the reaction is in the range of from about 90.degree. C. up to about 150.degree. C.;

(ii) the pressure over the reaction mass may vary from about 3 mm/Hg. (vacuum) up to about 1 atmosphere with a preferable pressure of between about 5 and about 100 mm/Hg. pressure;

(iii) the time of reaction may vary from about 5 up to about 15 hours with a preferred time of reaction of between about 6 and about 12 hours;

(iv) the mole ratio of aldehyde having the structure: ##STR88## or mixture of aldehydes having the structure: ##STR89## to alkyl anthranilate having the structure: ##STR90## may vary from about 1:1 up to about 1.25:1 of total aldehyde:alkyl anthranilate with a preferred mole ratio of between about 1:1 and about 1.1:1 aldehyde:alkyl anthranilate.

At the end of the reaction, the reaction mass may be separated and the reaction product purified as by fractional distillation of the schiff base or schiff base reaction product. From a practical standpoint when a reaction mixture is created which gives rise to preferred perfumery properties subsequent fractional distillation to the point of yielding an odor acceptable product is what is desired.

The following table sets forth reactants, schiff base reaction product structures (to the extent known) and organoleptic properties of the resulting products.

When one or more of the schiff bases and reaction products containing same of our invention is used as a food flavor adjuvant, the nature of the co-ingredients included with said schiff bases in formulating the product composition will also serve to alter the organoleptic characteristics of the ultimate foodstuffs treated therewith. As used herein in regard to flavors the term "alter" in its various forms means "supplying or imparting flavor character or notes to otherwise bland relatively tasteless substance or augmenting the existing flavor characteristic where a natural flavor is deficient in some regard or supplementing the existing flavor impression to modify its quality, character or taste".

As used herein, the term "foodstuff" includes both solid and liquid ingestible materials which usually do but need not have nutritional value. Thus, foodstuffs include soups, convenience foods, beverages, dairy products, candies, fruit cereals, soft drinks, snacks and the like.

Substances suitable for use herein as co-ingredients or flavoring adjuvants are well known in the art for such use being extensively described in the relevant literature. Apart from the requirement that any such material be "ingestibly" acceptable and thus non-toxic or otherwise non-deleterious nothing particularly critical resides in selection thereof.

The specific flavoring adjuvants selected for use may be either solid or liquid, depending upon the desired physical form of the ultimate product, i.e., foodstuff, whether simulated or natural, and should, in any event, be capable of providing an environment in which the schiff bases of our invention can be disbursed or admixed to provide a homogeneous medium. In addition, selection of one or more adjuvants, as well as the quantities thereof, will depend upon the precise organoleptic grape character desired in the finished product. Thus, in the case of flavoring compositions, ingredient selection will vary in accordance with the foodstuff to which the flavor and aroma are to be imparted. In contradistinction, in the preparation of solid products, e.g., simulated foodstuffs, ingredients capable of providing normally solid compositions should be selected such as various cellulose derivatives.

As will be appreciated by those skilled in the art, the amount in which the schiff bases of our invention employed in a particular instance can vary over a relatively wide range whereby its desired organoleptic effects (having reference to the nature of the product) are achieved. All parts and percentages given herein are by weight unless otherwise specified. Thus, correspondingly greater amounts would be necessary in those instances wherein the ultimate food composition to be flavored is relatively bland to the taste, whereas relatively minor quantities may suffice for the purposes of enhancing the composition merely deficient in natural flavor or aroma. Thus, the primary requirements is that amount which is effective, i.e., sufficient to alter the organoleptic characteristics of the parent composition, whether foodstuff per se or flavoring composition. Thus, the use of insufficient quantities in which the schiff bases of our invention will, of course, substantially vitiate any possibility of obtaining the desired results while excess quantities prove needlessly costly and in extreme cases, may disrupt the flavor-aroma balance, thus proving self-defeating. Accordingly, the terminology "effective amount" and "sufficient amount" is to be accorded a significance in the context of the present invention consistent with the obtention of desired flavoring effects.

Thus and with respect to ultimate food compositions, it has been found that quantities in which the schiff bases of our invention ranging from a small but effective amount, e.g., 0.02 parts per million up to about 50 parts per million by weight based on total composition are suitable. Concentrations in excess of the maximum quantity stated are not normally recommended since they fail to provide commensurate enhancement of organoleptic properties. In those cases wherein in which the schiff bases of our invention is added to the foodstuff as an integral component of the flavoring composition, it is, of course, essential that the total quantity of flavoring composition employed be sufficient to yield an effective schiff base concentration in the foodstuff product.

The composition described herein can be prepared according to conventional techniques well known as typified by cake batters and fruit juices and can be formulated by merely admixing the involved ingredients within the proportions stated in a suitable blender to obtain the desired consistency, homogeneity of dispersion, etc. Alternatively, flavoring compositions in the form of particulate solids can be conveniently prepared by admixing the schiff bases of our invention with, for example, gum arabic, gum tragacanth, carrageenan and the like and thereafter spray-drying the resultant mixture whereby to obtain the particulate solid product. Prepared flavor mixes in powder form, e.g., a raspberry flavored powder are obtained by mixing dried solid, components, e.g., starch, sugar and the like and the schiff bases of our invention in a dry blender until the requisite degree of uniformity is achieved.

One or more schiff bases prepared in accordance with the process of our invention and one or more auxiliary perfume ingredients including, for example, alcohols, aldehydes, ketones, terpinic hydrocarbons, nitriles, esters, lactones, natural essential oils and synthetic essential oils may be admixed so that the combined odors of the individual components produce a pleasant and desired fragrance, particularly, and preferably, in pine, floral and lavender fragrances. Such perfume compositions usually contain (a) the main note or the "bouquet" or foundation stone of the composition; (b) modifiers which round off and accompany the main note; (c) fixatives which include odorous substances which lend a particular note to the perfume throughout all stages of evaporation and substances which retard evaporation; and (d) topnotes which are usually low boiling, fresh smelling materials.

In perfume compositions, it is the individual components which contribute to their particular olfactory characteristics, however, the over-all sensory effect of the perfume composition will be at least the sum total of the effects of each of the ingredients. Thus, schiff base derivatives prepared in accordance with the process of our invention, can be used to alter, modify or enhance the aroma characteristics of a perfume composition, for example, by utilizing or moderating the olfactory reaction contributed by another ingredient in the composition.

The amount of schiff base derivatives prepared in accordance with the process of our invention which will be effective in perfume compositions as well as in perfumed articles (e.g., anionic, nonionic, cationic and zwitterionic solid or liquid detergents, soaps, fabric softener compositions, drier-added fabric softener articles, optical brightener compositions, perfumed polymers and textile sizing agents) and colognes depends on many factors, including the other ingredients, their amounts and the effects which are desired. It has been found that perfume compositions containing as little as 0.01% of schiff base derivatives prepared in accordance with the process of our invention and less than 50% of schiff base derivatives prepared in accordance with the process of our invention or even less (e.g., 0.005%) can be used to impart lemony, floral, green, ozoney, fruity, melony, citrus, piney, grape-like, woody, sweet and muguet aroma with anisic, fresh cut wood, ozoney, fresh air, floral and orange flower topnotes and anisic, woody, floral, green and citrus undertones to solid or liquid anionic, cationic, nonionic or zwitterionic detergents, fabric softener compositions, fabric softener articles, optical brightener compositions, textile sizing compositions, perfumed polymers or other products. The amount employed can range up to 70% of the fragrance components and will depend on considerations of cost, nature of the end product, the effect desired on the finished product and the particular fragrance sought.

The schiff base derivatives prepared in accordance with the process of our invention is useful (taken alone or together with other ingredients in perfume compositions) as (an) olfactory component(s) in detergents and soaps, space odorants and deodorants, perfumes, colognes, toilet water, bath preparations, such as creams, deodorants, hand lotions and sun screens; powders, such as talcs, dusting powders, face powders, and perfumed polymers and articles of manufacture produce from said perfumed polymers. When used as (an) olfactory component(s) as little as 0.2% of schiff base derivatives prepared in accordance with the process of our invention will suffice to impart an intense lemony, floral, green, ozoney, fruity, melony, citrus, piney, grape-like, woody, sweet and muguet aroma with anisic, fresh cut wood, ozoney, fresh air, floral and orange flower topnotes and anisic, woody, floral, green and citrus undertones to floral, piney, lemony and rose and fresh air formulations. Generally, no more than 6% of one or more schiff bases of our invention based on the ultimate end product is required in the perfumed article composition. Accordingly, the range of schiff bases in the perfumed articles is from about 0.2% by weight of the schiff bases up to about 6% by weight based on the perfumed article. In addition, the perfume composition or fragrance composition of our invention can contain a vehicle or carrier for one or more of the schiff base derivatives prepared in accordance with the process of our invention. The vehicle can be a liquid, such as a non-toxic alcohol, e.g., ethyl alcohol, a non-toxic glycol, e.g., propylene glycol or the like. The carrier can also be an absorbent solid, such as a gum (e.g., gum arabic , guar gum or xanthan gum) or components for encapsulating the composition (such as gelatin) as by coacervation; or such as urea-formaldehyde polymer forming a capsule shell around a liquid perfumed center).

Our invention also relates to the utilization of controlled release technology for the controlled release of perfumes into gaseous environments from polymers such as mixtures of epsilon polycaprolactone polymers and polyethylene which polyepsilon caprolactone polymers are defined according to at least one of the structures: ##STR146## wherein "n" is from about 50 up to about 1,200 with the proviso that the average "n" in the system varies from about 150 up to about 700 according to the mathematical statement:

with the term .sup.n being the average number of repeating monomeric units for the epsilon polycaprolactone polymer. The perfumed material's release rate from such polymer mixture is close to "zero order". As a general rule, the release rate in a polymeric matrix is proportional to t.sup.-1/2 until about 60% of the functional fluid is released from the polymeric matrix. The release rate thereafter is related exponentially to time as a general rule according to the equation: ##EQU1## wherein k.sub.1 and k.sub.2 are constants. According to Kydonieus, "Controlled Release Technologies: Methods, Theory, and Applications" (cited, supra, the amount of perfume composition released is proportional to time as long as the concentration of perfume material present, e.g., the schiff bases of our invention is higher than the solubility of the agent in the matrix. Thus, such dispersed systems are similar to the dissolved systems except that instead of a decreased release rate after 60% of the perfume material has been emitted, the relationship holds almost over the complete release curve. Kydonieus further states, that if one assumes that the release of functional fluid by diffusion is negligible in monolithic erodible systems, the speed of erosion will control the release rate and release by erosion by a surface-area-dependent phenomenon, the release constant (zero order) as long as the surface area does not change during the erosion period. This is the case with the polymers containing the schiff bases of our invention.

The polyepsilon caprolactone polymers useful in practicing our invention are more specifically described in the brochure of the Union Carbide Corporation, 270 Park Avenue, New York, N.Y. 10017, entitled "NEW POLYCAPROLACTONE TERMOPLASTIC POLYMERS PCL-300 AND PCL-700". These polyepsilon caprolactone polymers are composed of a repeating sequence of non-polar methylene groups and relatively polar ester groups. The average number of repeating monomeric units varies between 150 and 700 depending on the particular "PCL" number. Thus, regarding PCL-300 the average number of repeating monomeric units is about 300. Regarding PCL-700, the average number of repeating monomeric units is 700.

The polyepsilon caprolactone homopolymers which are ultimately taken in admixture with such materials as polyethylene useful in the practice of our invention may also be stabilized using stabilizers as defined in U.S. Pat. No. 4,360,682 issued on Nov. 23, 1982, the specification for which is incorporated herein by reference. The stabilizing materials which stabilize the polyepsilon caprolactone useful in conjunction with our invention against discoloration are dihydroxybenzenes such as hydroquinone or compounds having the formula: ##STR147## in which R.sub.1 alkyl of from 1 to 8 carbon atoms, and R.sub.2 is hydrogen or alkyl of 1 to 8 carbon atoms. It is preferable to have such stabilizer in the polyepsilon caprolactone homopolymer in an amount of from about 100 to 500 ppm. Such stabilizers do not interfer with the functional fluids dissolved and/or adsorbed into the polymeric matrix.

The method of incorporating the schiff bases of our invention or perfume compositions containing same into the polymers may be according to the technique of U.S. Pat. No. 3,505,432 issued on Apr. 7, 1970 (the specification for which is incorporated by reference herein) or U.S. Pat. No. 4,247,498 issued on Jan. 27, 1981, the disclosure of which is incorporated by reference herein.

Thus, for example, a first amount of liquid polyethylene-polyepsilon caprolactone polymer mixture (50:50) is mixed with one of the schiff bases of our invention. Drops are formed from the mixture and the drops are solidified. The solidified drops are then melted, if desired, with a second amount of unscented low density polyethylene, for example, or polypropylene, for example. Usually, but not necessarily, the second amount of polymer is larger than the first amount. The resulting mixture thus obtained is solidified subsequent to or prior to ultimate casting into a utilitarian shape.

Thus, in accordance with one aspect of our invention the imparting of scent is effected in two stages. In a first stage, a 50:50 (weight:weight) polyepsilon caprolactone, e.g., PCL-700: polyethylene in molten form is admixed with a high percentage of one of the schiff bases of our invention and the mixture is solidified in the form of pellets or beads. These pellets or beads thus contain a high percentage of schiff bases (e.g., up to 45% by weight of the entire mixture) and may be used as "master pellets" which thereafter, in a second stage, if desired, may be admixed and liquified with additional polymers such as additional polyethylene or mixtures of polyethylene and polyepsilon caprolactone in an unscented state, or unscented polypropylene. In addition, additional polymers or copolymers may be used, for example, copolymers specified and described in United Kingdom Patent Specification No. 1,589,201 published on May 7, 1981, the specification for which is incorporated by reference herein.

In accordance with the present invention at least one of the schiff bases of our invention is added to the polymer in a large closed container or drum which is maintained under controlled temperature conditions while the polymer in a melted condition is mixed with at least one of the schiff bases under agitation.

In order that the perfume be added uniformly to the polymer, the temperature of the melt is constantly controlled during the process. The polymer-perfume mixture is then directed through an elongated conduit or pipe element having a plurality of orifices adjacent to the lower most portion thereof. The polymer enriched by at least one of the schiff bases of our invention is permitted to drip through the orifices onto a continuously moving, cooled conveyor upon which the polymer containing at least one of the schiff bases of our invention solidifies into small size pellets with the perfume imprisoned therein. The apparatus useful in conjunction with this process advantageously includes a conveyor of a material which will not adhere to the polymer which contains at least one of the schiff bases of our invention.

In order that the droplets form into uniform pellets or beads, the conveyor is continuously washed with a liquid such as water to maintain the surface relatively cool. The pellets are delivered by the conveyor into a container and packaged for shipment.
