THERMOPLASTIC RESIN COMPOSITION AND MOLDED ARTICLES

摘要

A thermoplastic resin composition which gives a molded piece having good surface appearance even when extruded at a high extrusion rate, keeps impact resistance even after heat exposure, and is little contaminated during the production. Namely, a composition comprising a polyamide, a polyphenylene ether and a block copolymer, wherein the block copolymer is a mixture of a block copolymer having a number−average molecular weight of less than 120,000 and a block copolymer having a number−average molecular weight of 120,000 or above.
