Abstract
Abstract A novel thermoplastic resin composition excellent in heat resistance, impact resistance, hardness is provided which comprises 100 parts by weight of a composition comprising (A) 5-95% by weight of a polyphenylene ether prepared by oxidation polymerization of at least one phenol compound represented by the formula: <IMAGE> wherein R1, R2, R3, R4 and R5 which may be identical or different and represent a hydrogen atom, a halogen atom, a substituted or unsubstituted hydrocarbon residue, with a proviso that at least one of them is a hydrogen atom and (B) 95-5% by weight of a polyamide and 5-100 parts by weight of (C) a copolymer of an ethylene- alpha -olefin copolymer rubber with an alkenyl aromatic compound and an unsaturated carboxylic acid or its anhydride. This composition may further contain 0.01-30 parts by weight of an epoxy compound (D) for 100 parts by weight of the composition of (A) and (B).
