Thermoplastic resin compositions.

摘要

A thermoplastic resin composition comprising a polyphenylene ether and a polyamide and an impact strength modifier block copolymer having the structure A-B-A (A or B is styrene) partially dispersed in the polyphenylene ether has layered or spherical micro-phase separation structure of about 0.02 - 0.07 mu m thickness or diameter. The thermoplastic resin composition is produced by (1) melt kneading (i) at least one compatibilizing agent in an amount effective for compatibilization and (ii) a polyphenylene ether and then (2) adding (iii) a polyamide in an amount necessary for formation of continuous phase and (iv) an impact strength modifier having the structure A-B-A and melt keading the mixture at a maximum shear rate of 700 sec <-><1> or more.
