Abstract
The thermoplastic resin composition according to the present invention comprises (A) about 20˜95 parts by weight of a rubber-modified polystyrene resin composed of (a1) about 10˜60% by weight of a styrene-containing graft copolymer resin containing about 10˜60% by weight of a rubber and about 90˜40% by weight of a styrene-acrylonitrile copolymer, the styrene-acrylonitrile copolymer containing about 0.5˜10% by weight of acrylonitrile, and (a2) about 90˜40% by weight of a styrene-containing copolymer resin containing 0˜20% by weight of a rubber; and (B) about 5˜80 parts by weight of a polyphenylene ether.
