Perfume-containing resin
FIELD OF THE INVENTION 
     The present invention relates to a perfume-containing resin which is produced by polymerizing diethylene glycol bis(allyl carbonate) in the presence of a perfume. The perfume-containing resin emits a well-balanced fragrance over a long period of time. 
     BACKGROUND OF THE INVENTION 
     Heretofore, the air freshners or odorants have been available in the form of aerosol, gel, liquid, powder, and synthetic resin product. Many attempts have been made to incorporate a perfume into a synthetic resin. However, effective air freshners or odorants cannot be made by such a simple incorporation, because a perfume and a synthetic resin are not compatible with each other and the perfume incorporated into the resin seeps through and rapidly wastes from the surface of the resin, or the perfume is sealed inside the resin and does not diffuse to the surface of the resin. For example, thermoplastic resins of linear hydrocarbons such as polyethylene and polypropylene have a poor gas permeability, whereas polystyrene resin and polyvinyl acetate resin are excessively permeable to a gas. Thus, those materials are not suitable as a substrate for air freshners or odorants. 
     Several methods have been proposed to overcome these disadvantages of synthetic resin products; a method comprising supporting a hydrophylic polymer of hydrophylic acrylate or methacrylate on a fragrant substance, a method comprising using a chlorinated product of a polyethylene or polyethylene copolymer, a method comprising mixing and melting a perfume into a low molecular weight polyolefin resin and incorporating the resulting pellets into a high molecular weight polyolefin resin, and method comprising mixing a perfume with or impregnating and absorbing a perfume into an ethylene-acrylate ester copolymer or copolymers of ethylene and various acrylic acid esters. However, in some applications of air freshners or ordorants, special properties such as hardness, clarity, and colorability are required. 
     SUMMARY OF THE INVENTION 
     As a result of extensive investigations to develop air freshners or odorants which emit a well-balanced fracrance uniformly over a long period of time and have some characteristic properties, it was found that this object can be achieved by a polymer of diethylene glycol bis(allyl carbonate), into which a perfume is incorporated. 
     Accordingly, an object of this invention is to provide a perfume-containing resin which is produced by polymerizing diethylene glycol bis(allyl carbonate) in the presence of a perfume.

     DETAILED DESCRIPTION OF THE INVENTION 
     Diethylene glycol bis(allyl carbonate) used in this invention is a commercially available product, CR-39 (PPG Industries, Inc., U.S.A.). The polymer thereof is an organic glass having optical characteristics and is widely used as spectacles lenses due to its superior properties such as lightness, impact resistance (safety), processabilily, and dyeability, as compared with an inorganic glass. 
     According to the embodiment of this invention, a polymerization initiator is added to diethylene glycol bis(allyl carbonate) and then a perfume is well mixed therein. The resulting mixture is cast into a mold of desired shape and uniformly polymerized therein at a prescribed temperature. The polymerization (curing) is conducted at 5° to 100° C. for 1 to 100 hours, preferably at 45° to 50° C. for 5 to 10 hours, and then further conducted at 85° to 90° C. for 3 to 10 hours. 
     In commercial scale production a mixture of diethylene glycol bis(allyl carbonate), a polymerization initiator, and a perfume is cast into a mold constructed by a glass mold and a synthetic resin gasket and then cured by the method of heating. Curing may also be conducted by adding a photopolymerizing catalyst using a method such as irradiating with an ultraviolet ray lamp, irradiating with a mercury lamp, etc. After polymerization is completed, the perfume-containing resin is taken out from the mold. 
     The diethylene glycol bis(allyl carbonate) monomer may be copolymerized with at least one of other polymerizable monomers such as diallyl phthalate, benzylmethacrylate, methacrylate, diallyl maleate, diallyl fumarate, diallyl succinate, diallyl crotonate, diallyl benzoate, and diallyl diglycol ester, as disclosed in Unexamined Published Japanese Patent Application No. 61411/1981, to obtain a multicomponent polymer. The amount of the other polymerizable comonomer is preferably 50 wt% or less based on the weight of the diethylene glycol bis(allyl carbonate). Further, a flame retardant, UV absorber, weathering agent, antistatic agent, colorant (such as dyestuff), and the like, can be added. 
     The polymerization initiator which can be used includes diisopropyl peroxydicarbonate di-sec-butyl peroxydicarbonate, lauroyl peroxide, and azobisisobutyronitrile. Use of benzoyl peroxide tends to require a long curing. 
     The amount of the polymerization initiator used is 0.1 to 25 wt%, preferably 1 to 15 wt%, based on the weight of diethyleneglycol bis(allyl carbonate). 
     The perfume which can be used includes a natural perfume, a synthetic perfume, a synthetic essential oil and a natural essential oil. 
     Examples of the synthetic perfume include terpenic hydrocarbons, esters, ethers, alcohols, aldehydes, phenols, ketons, acetals, oximes and mixtures thereof. 
     Examples of the terpenic hydrocarbons include lime terpene, lemon terpene and limonen dimer. 
     Examples of the esters include γ-undecalactone, ethyl methyl phenyl glycidate, allyl caproate, amyl salicylate, amyl benzoate, amyl acetate, benzyl acetate, benzyl benzoate, benzyl salicylate, benzyl propionate, butyl acetate, benzyl butyrate, benzyl phenylacetate, cedryl acetate, citronellyl acetate, citronellyl formate, p-cresyl acetate, 2-t-pentyl-cyclohexyl acetate, cyclohexyl acetate, cis-3-hexenyl acetate, cis-3-hexenyl salicylate, dimethylbenzyl acetate, diethyl phthalate, δ-decalactone dibutyl phthalate, ethyl butyrate, ethyl acetate, ethyl benzoate, fenchyl acetate, geranyl acetate, γ-dodecalatone, methyl dihydrojasmonate, isobornyl acetate, β-isopropoxyethyl salicylate, linalyl acetate, methyl benzoate, o-t-buthylcylohexyl acetate, methyl salicylate, ethylene brassylate, ethylene dodecanoate, methyl phenyl acetate, nopyl acetate, phenylethyl isobutyrate, phenylethylphenyl acetate, phenylethyl acetate, methyl phenyl carbinyl acetate, 3,5,5-trimethylhexyl acetate, terpinyl acetate, triethyl citrate, p-t-butylcyclohexyl acetate and vetiver acetate. 
     Examples of the ethers include p-cresyl methyl ether, diphenyl ether, 1,3,4,6,7,8-hexahydro-4,6,7,8,8-hyxamethyl cyclopenta-γ-2-benzopyran and phenyl isoamyl ether. 
     Examples of the alcohols include n-octyl alcohol, n-nonyl alcohol, β-phenylethyldimethyl carbinol, dimethyl benzyl carbinol, carbitol dihydromyrcenol, dimethyl octanol, hexylene glycol linalool, leaf alcohol, nerol, phenoxyethanol, γ-phenylpropyl alcohol, β-phenylethyl alcohol, methylphenyl carbinol, terpineol, tetraphydroalloocimenol, tetrahydrolinalool and 9-decen-1-ol. 
     Examples of the aldehydes include n-nonyl aldehyde, undecylene aldehyde, methylnonyl acetaldehyde, anisaldehyde, benzaldehyde, cyclamenaldehyde, 2-hexylhexanal, α-hexylcinnamic aldehyde, phenyl acetaldehyde, 4-(4-hydroxy-4-methylpentyl)-3-cyclohexene-1-carboxyaldehyde, p-t-butyl-α-methylhydrocinnamic aldehyde, hydroxycitronellal, α-amylcinnamic aldehyde and 3,5-dimethyl-3-cyclohexene-1-carboxyaldehyde. 
     Examples of the phenols include methyl eugenol. 
     Examples of the ketones include l-carvone, α-damascon, ionone, 4-t-pentylcyclohexanone, 3-amyl-4-acetoxytetrahydropyran, menthone, methylionone, p-t-amycyclohexanone and acetyl cedrene. 
     Examples of the acetals include phenylacetaldehydedimethyl acetal. 
     Examples of the oximes include 5-methyl-3-heptanon oxime. 
     The perfume can be used alone or as mixtures thereof. 
     The amount of the perfume added is 1 to 60 wt%, preferably 5 to 45 wt%, based on the weight of the diethylene glycol bis(allyl carbonate). If the amount of perfume is too small, the life as the air freshners or odorants is short and the commercial value thereof is lost. If the amount of perfume is too large, the curing time becomes long, so that the productivity is reduced, the product obtained is soft due to insufficient polymerization, or cracking occurs on the product. 
     The perfume-containing resin is greatly influenced depending upon the type of perfume used such that the inherent fragrance of a perfume changes, a resin which is inherently colorless and transparent shows coloration or the hardness of a resin is adversely affected. Therefore, the perfume used must be carefully selected according to the purpose of use of the perfume containing resin. 
     Regarding the influence of the perfume to the resin, there is no perfume showing a remarkable change of the fragrance, but as explained in the following Examples, a relatively low boiling perfume, particularly benzaldehyde and ethyl acetate, shows the change of fragrance and the intensity of fragrance is decreased. 
     Examples of the perfumes which tend to color a colorless and transparent resins in light yellow, include n-nonylaldehyde, methylnonylacetaldehyde, benzaldehyde, cyclamenaldehyde, citral, cinnamic aldehyde, cedryl acetate, eugenol, isoeugenol, methyl eugenol, cis-jasmone, 1-carvone, γ-methyl ionone, methyl dihydrojasmonate, α-hexylcinnamic aldehyde, phenylacetoaldehyde, 4-t-phenylcyclohexanone, hydroxycitronellal, methyl anthranilate, α-amyl cinnamic aldehyde, 5-methyl-3-pentanoneoxime, vetiver aldehyde, acetyl cedrene, limonene dimer, etc. Of these perfumes, the perfumes which have the particularly strong coloration tendency, are cinnamic aldehyde, α-amylcinnamic aldehyde and α-hexylcinnamic aldehyde which have a double bond conjugated with the aromatic nucleus and an aldehyde group; eugenol which is a phenol derivative; methyl anthranilate which is a nitrile or nitrogen-containing compound; and 5-methyl-3-heptanoneoxime. 
     The perfumes which tend to lower the hardness of the resin and cause the cured resin to remain in the liquid or gell state include cinnamic alcohol, citronellal, citral, citronellol, caryophyllene, cedrene, Cedar H (a product of Takasago Corporation), cinnamic aldehyde, cinnamyl acetate, cis-jasmone, eugenol, isoeugenol, and methyl anthranilate. Of these perfumes, the perfumes which particularly affect the curing, whereby the polymer is not solidified and remains in the liquid state are cinnamic alcohol, citral, caryophyllene, Cedar H (a product of Takasago Corporation), cinnamic aldehyde, cinnamyl acetate, eugenol, isoeugenol, and methyl anthranilate. 
     Therefore, for example, to the resins having the purpose of use which requires colorless, transparent and hard properties, use of a perfume which impairs these properties, for example, cinnamic aldehyde, should be avoided. 
     The perfume-containing resin prepared as described above emits the perfume slowly and uniformly over a long period of time and has excellent characteristics as air freshners or odorants. Further, the inherent characteristics of the resin such as transparency, easy coloration with dye and excellent hardness are not deteriorated. Thus, the perfume-containing resin has a wide use as a base material for pendants, brooches, buttons, cuff links, tiepins and other personal ornaments; room ornaments; desk lamp shade; furniture knobs and pulls; key holders; sunglasses (spectacle lenses); mirrors; telephone sets; flower vases; rulers, cardboards (laid under writing paper) and other writing materials; and air freshners or odorants for cars and bathrooms. 
     The invention is now described in detail by reference to the following examples. 
     EXAMPLES 1 TO 121 
     A 10 ml cylindrical glass bottle was filled in a volume of 3/4 with diethylene glycol bis(allyl carbonate) containing 4 wt% of diisopropyl peroxydicarbonate as a polymerization initiator. A single perfume was then added to the glass bottle and well mixed. The glass bottle was completely filed with diethylene glycol bis(allyl carbonate), followed by shaking for thorough mixing. The bottle was covered and placed in an oven to polymerize by heating. The heating conditions were as follows: 
     Examples 1 to 33: Heating at 45° to 50° C. for 5 hours, gradually increasing the temperature to 90° C. over 2 hours, and then heating at 90° to 95° C. for 11 hours. 
     Examples 34 to 69: Heating at 40° to 45° C. for 7 hours, gradually increasing the temperature to 90° C. over 4 hours, and then heating at 90° to 95° C. for 13 hours. 
     Examples 70 to 121: Heating at 40° to 45° C. for 7 hours, gradually increasing the temperature to 90° C. over 1 hour, and then heating at 90° to 95° C. for 11 hours. 
     After polymerization was completed, the bottle was cooled to room temperature and the resulting resin was observed. The solidified resin was separated from the bottle by breaking the bottle. The results obtained are shown in Table 1 below.

     31.48 g of diethylene glycol bis(allyl carbonate) containing 4 wt% of diisopropyl peroxydicarbonate as a polymerization initiator was placed in a stainless steel oval mold having a thickness of 5 mm and a volume of 35 ml in volume and 3.50 g of the compounding perfume was added thereto. After thoroughly mixing, the mold was covered and heated in an oven. The temperature was kept at 45° to 50° C. for 7 hours, and then the temperature was gradually increased over 2 hours, followed by heating at 92° to 98° C. for 10 hours. After polymerization was completed, the mold was cooled to room temperature and the molded product was taken out. The molded product had the weight of 34.97 g and was a hard product like a colorless, transparent glass. Five perfumers of long experience for ten years or more made comparison on the fragrance between the compounding perfume initially added and the molded product. As a result, it was all the evaluation that there was no substantial change on the fragrance therebetween. 
     The molded product was allowed to stand in a chamber having an air flow of 2.5 m/sec and exposed to the air flow to observe the volatility of the perfume. The molded product was weighed every week. The results obtained are shown in Table 2.

     A is the amount of volatilized perfume and 
     B is the weight of perfume added initially. 
     The relationship thereof is shown in the FIGURE. As apparent from the FIGURE, the volatility of perfume is almost linear. This indicates that the perfume volatilizes uniformly. According to the evaluation on the fragrance by the same perfumers every weekend, the initially added compounding perfume did not almost change the fragrance and the molded product kept emitting the fragrance of the compounding perfume over four weeks. 
     EXAMPLE 123 
     0.8 g of the compounding perfume prepared in Example 122 and 0.7 g of diisopropyl peroxycarbonate were dissolved in 20 g of diethylene glycol bis(allyl carbonate). The resulting solution was cast into a mold for molding spectacle lenses, the upper and bottom portions of which were sealed with glass molds and the circumference of which was sealed with a plastic gasket sealing the edges of the glass molds. The mold was placed in an oven. The temperature in the oven was maintained at 45° to 50° C. for 8 hours, gradually increased to 90° C. over 8 hours, and then kept at 90° to 95° C. for 2 hours. After polymerization was completed, the mold was cooled to room temperature and the molded product was taken out. The molded product was thoroughly washed with trichloroethylene. The product obtained had a weight of 21.5 g and was colorless, transparent spectacle lens which emits a fracgrance. The lens had a surface hardness of 6 to 8  as measured according to JIS K6911 using a Barcol hardness tester. The lens was dyed by dipping in a dye solution of Mars Orange Lot No. M-122 (made by Asahi Glass Co., Ltd.) at 83° C. for about 8 seconds, so that the lens had a luminous transmittance of 85%. After thorough water washing and drying, the lens was inspected in the same manner as in the ordinary spectacle lenses and the same results as obtained in the ordinary spectacle lenses were obtained. The lenses thus pepared were made into a pair of spectacles. In performance test of the spectacles, the lenses did not cause any practical problem such as slipping off from the frame due to vibrations and temperature change. As to the light resistance, the lenses passed the fadeometer test for 100 hours.
