Thermoplastic resin compositions.

摘要

A thermoplastic resin composition contains a propylene polymeride and a graft copolymer having an olefin homo(co-polymer portion and a vinyl copolymer portion. The olefin homo(co-polymer portion occupies 5 to 95 % by weight of the graft copolymer and the vinyl copolymer portion occupies the remainder. The vinyl copolymer portion of the graft copolymer contains at least one functional group selected from the group consisting of an epoxy group, a carboxyl group, a hydroxyl group and an amino group. One of the olefin homo(co-polymer portion and the vinyl copolymer portion form a dispersed phase in the other with a particle size of 0.001 to 10 mu m. Thus, the graft copolymer has a multi-phase structure.
