POLYPHENYLENE ETHER RESIN COMPOSITION

A resin composition comprising: A) 10 to 90 parts by weight of a polyphenylene ether resin, (B) 8 to 88 parts by weight of an ABS resin, (C) 1 to 30 parts by weight of a first graft copolymer selected from the group consisting of (C-I) a graft copolymer which is obtainable by polymerizing a monomer mixture comprising an aromatic vinyl compound and at least one other compound copolymerizable therewith in the presence of a polymer (C-1) comprising an unsaturated nitrile compound, an aromatic vinyl compound and at least one other vinyl compound copolymerizable therewith and has a vinyl group at least at one of the molecular ends, and (C-II) a graft copolymer which is obtainable by polymerizing at least one vinyl compound in the presence of a polymer (C-1) and a polymer (C-2) comprising the aromatic vinyl compound and at least one other compound copolymerizable therewith except unsaturated nitrile compounds and has a vinyl group at least at one of the molecular ends, (D) 0 to 80 parts by weight of HIPS, and (E) 1 to 30 parts by weight of a second graft copolymer which is obtainable by polymerizing a monomer mixture comprising an unsaturated nitrile compound, an aromatic vinyl compound and at least one other vinyl compound copolymerizable therewith in the presence of a polymer which comprises an aromatic vinyl compound and at least one other vinyl compound copolymerizable therewith except unsaturated nitrile compounds and has a vinyl group at least at one of the molecular ends, provided that the second graft polymer is used in combination with the first graft copolymer (C-I).
