ABSTRACT:
A thermoplastic resin composition comprising: (I) a rubber-modified thermoplastic resin, and (II) a transparent thermoplastic resin, a thermoplastic elastomer or combination thereof, provided that said resin (I) is excluded from component (II), wherein the rubber-modified thermoplastic resin (I) is a resin prepared by polymerizing (B) 30-100% by weight of at least one member selected from the group consisting of an aromatic alkenyl compound monomer and an alkyl (meth)acrylate monomer and (C) 70-0% by weight of at least one other monomeric compound copolymerizable therewith, in the presence of 5-45% by weight of (A) a hydrogenated diene copolymer of component (I) obtained by hydrogenating a diene copolymer comprising a random copolymer of 50% by weight or more of at least one conjugated diene and 50% by weight or less of an alkenyl aromatic compound until at least 70% by weight of the olefinic unsaturation of the diene copolymer is hydrogenated.
