Abstract
Disclosed is a thermoplastic resin composition comprising a polyphenylene ether and a polyamide and excellent in impact strength wherein an impact strength modifier having structure A--B--A (A or B is styrene) is partially dispersed in said polyphenylene ether and has layered or spherical structure of about 0.02-0.07 .mu.m. A process for producing the thermoplastic resin composition is also disclosed which comprises (1) previously 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 structure A--B--A (A or B is styrene) and melt kneading the mixture at a maximum shear rate of 700 sec.sup.-1 or more.
