ABSTRACT THERMOPLASTIC RESIN COMPOSITION 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 µm. A process for producing the thermoplastic resin composition is also disclosed which comprised (1) previously melt kneading (i) at least one compatibi- lizing agent in an amount effective for compatibili- zation 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-1 or more.
