Clear perfumed polyamide resin and method of making it

Abstract

Abstract Bodies of clear substantially cosolvent free polyamide resin containing perfume oil in the range of small but effective amounts up to the maximum proportion that yields a clear resin, usually up to about 30% by weight. The bodies may be in the form of jewelry, decorative castings, coatings on substrates and the like. The method comprises heating a soluble resin, preferably an optically clear resin composed of cosoluble components having a relatively narrow and low molecular weight range, e.g., about 6,000 to 9,000, until it is pourable and stirrable, e.g., to about 120*C., blending up to 30% of a perfume oil, e.g., about 12% by weight, into the melt until a uniform mixture is obtained, and cooling the mixture to solidify it, preferably rapidly as by quenching in cold water. The product so obtained is then formed into useful objects, e.g., jewelry, by heat and pressure, decorative castings, coatings on substrates such as Christmas tree ornaments and electric light bulbs. Alternatively the perfume is blended into the resin in the feed line of a molding machine in which the perfumed resin bodies are fashioned directly.
