Abstract
Abstract A thermoplastic resin composition which comprises: (A) 100 parts by weight of: (i) a resin composition comprising 5-95% by weight of a polyphenylene ether obtainable by oxidation polymerisation of at least one phenol compound represented by the formula: wherein R¹, R², R³, R⁴ and R⁵, which may be identical or different, each represents a hydrogen atom, a halogen atom or a substituted or unsubstituted hydrocarbon group, and at least one of R¹ to R⁵ is a hydrogen atom, or (ii) a polyphenylene ether-based resin composition comprising said polyphenylene ether and a polystyrene, and 95-5% by weight of a polyamide resin; (B) 5 - 50 parts by weight of a saturated rubber obtainable by grafting 5 - 100 parts by weight of an aromatic vinyl compound onto 100 parts by weight of a saturated rubber and allowing 0.05 - 10 parts by weight of a compatibilising agent to react with said rubber, the grafting degree of said aromatic vinyl compound being 50% by weight or more; and (C) 0.05 - 20 parts by weight of a compatibilising agent.
