Nicht entflammbare thermoplastische Harzzusammensetzung

A flameproof thermoplastic resin composition of the present invention comprises (A) 40 to 95 parts by weight of a rubber modified styrene-containing resin composed of (a1) 20 to 100% by weight of a styrene-containing graft copolymer resin containing 18 to 50% by weight of acrylonitrile of copolymer excluding rubber, and (a2) 0 to 80% by weight of a styrene-containing copolymer containing 18 to 50% by weight of acrylonitrile; (B) 5 to 60 parts by weight of a polyphenylene ether resin; (C) 2 to 40 parts by weight of a styrene-containing copolymer or a styrene-containing graft copolymer which uses optionally to 60% by weight of rubber, having 5 to 18% by weight of an acrylonitrile in the copolymer excluding rubber, per 100 parts by weight of the sum of (A) and (B); and (D) 5 to 30 parts by weight of a triphenyl phosphate per 100 parts by weight of the sum of (A) and (B). The flameproof thermoplastic resin composition may further comprises 0 to 50 parts by weight of an anti-dripping agent, an impact modifier, a plasticizer, a heat stabilizer, an oxidation inhibitor, a light stabilizer, a compatibilizer, a pigment, a dye and/or an inorganic filler on the basis of 100 parts by weight of the base resin.
