PURPOSE:To obtain a thermoplastic resin composition having excellent impact resistance and weather resistance, improved luster and appearance by blending a specific hydrogenated (random) diene-based (co)polymer with a styrene-based resin in a specific ratio. CONSTITUTION:5-60wt.%, preferably 7-40wt.% hydrogenated (random) diene- based (co)polymer having >=70wt.%, preferably >=90wt.% hydrogenated olefinic unsaturated bond of the (co)polymer prepared by hydrogenating a conjugated diene-based polymer (e.g. one comprising monomer such as butadiene) or a random copolymer comprising >=50wt.%, preferably 65-95wt.% conjugated diene monomer and <=50wt.%, preferably 5-35wt.% vinyl aromatic compound (e.g. styrene) is blended with 40-95wt.%, preferably 60-93wt.% styrene-based resin (preferably polystyrene) in a molten state to give a thermoplastic resin composition. |
