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).
A thermoplastic resin composition 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 represent by the formula: ##STR6## wherein R 1 , R 2 , R 3 , R 4 and R 5 which may be identifical of different and represent a hydrogen atom, a halogen atom, a substituted or unsubstituted hydrocarbon residue, with provision that at lest 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-α-olefin copolymer rubber with an alkenyl aromatic compound and an unsaturated carboxylic acid or its anhydride, in which the addition amount of the unsaturated carboxylic acid or its anhydride is 0.3-5% by weight of the ethylene-α-olefin copolymer rubber, and the weight ratio of the alkenyl aromatic compound to the unsaturated carboxylic acid or its anhydride is 0.2-5.
