Thermoplastic resin compositions.

摘要

A thermoplastic resin composition comprising (A) 60 to 99 parts by weight of at least one thermoplastic resin selected from the group consisting of polyamide resins, polymethacrylimide resins and polyetherimide resins and (B) 1 to 40 parts by weight of a polyorganosiloxane graft copolymer obtained by graft-polymerizing one or more kinds of vinyl monomer containing at least an epoxy group-containing vinyl monomer onto a polyorganosiloxane compound rubber having a structure in which a polyorganosiloxane rubber component and a polyalkyl (meth)acrylate rubber component have been inseparably united with each other, the total amount of both the components (A) and (B) being 100 parts by weight. The thermoplastic resin composition of the present invention is excellent in impact resistance, so that it can be used under severer conditions than do the conventional ones. Consequently, the thermoplastic resin composition has a characteristic that development of a wider range of use becomes possible.
