Abstract
Abstract A thermoplastic resin composition which comprises: 100 parts by weight of a composition comprising: (A) 5 to 95% by weight of a polyphenylene ether prepared by oxidation polymerization of at least one phenol of formula: wherein R 1 , R 2 , R 3 , R 4 and R 3 , which may be identical or different, represent hydrogen, a halogen or a substituted or unsubstituted hydrocarbon group, with the proviso that at least one of R, to R 5 is hydrogen; and (B) 95 to 5% by weight of a polyamide; and 5 to 100 parts by weight of (C) a copolymer of an ethylene-α -olefin copolymer rubber, an alkenyl aromatic compound and an unsaturated carboxylic acid or an anhydride thereof.
