THERMOPLASTIC RESIN COMPOSITION AND METHOD FOR PREPARING THE SAME

摘要

There is here provided a thermoplastic resin composition which comprises (I) 50 to 99% by weight of an aromatic polyester resin, and III) 50 to 1% by weight of a multiphase structure thermoplastic resin which is composed of 5 to 95% by weight of at least one ethylene copolymer selected from the group consisting of epoxy group-containing ethylene copolymers, ethylene-unsaturated carboxylic acids, alkyl ester copolymers and metallic salts of the ethyleneunsaturated carboxylic acids, and ethylene-vinyl ester copolymers, and 95 to 5% by weight of a vinyl polymer or copolymer obtained from at least one vinyl monomer, either of both the components possessing a dispersion phase where each particle has a diameter of 0.001 to 10 .mu.m. A method for preparing the above-mentioned thermoplastic resin composition is also provided here.
