Abstract

Perfumed composites of ethylene and polar monomer copolymers, such as vinyl acetate and ethyl acrylate, are disclosed. Shaped bodies prepared from such composites faithfully retain the fragrance of the perfume oil for periods up to a year and more.

Claims

1. A thermoplastic resin body consisting essentially of a thermoplastic copolymer of ethylene and about 6 to 60% by weight of a polar vinyl monomer selected from the class consisting of

(a) vinyl acetate;

(b) ethyl acrylate;

(c) methyl acrylate;

(d) butyl acrylate; and

(e) acrylic acid and about 1 to 30% by weight of perfume oil.

2. The thermoplastic resin body of claim 1 wherein the thermoplastic copolymer is comprised of ethylene and about 6 to 18% by weight ethyl acrylate.

3. The thermoplastic resin body of claim 1 wherein the thermoplastic copolymer is comprised of ethylene and about 9 to 60% by weight of vinyl acetate.
