PURPOSE:To obtain a composition useful as OA(office automation) device parts and sliding materials, having excellent impact strength, luster and sliding properties, comprising a rubber modified styrene based resin composition having occlusion structure and polyorganosiloxane having specific viscosity CONSTITUTION:A styrene-based resin composition comprising (A) 100 pts.wt. resin composition which consists essentially of a rubber modified styrene-based resin composition having occlusion structure in a dispersed rubber state obtained by polymerizing styrene with an arbitrarily copolymerizable monomer in the presence of a rubber-like polymer (preferably styrene-butadiene block polymer) by bulk-suspension two-stage polymerization and <=45wt.%, preferably <=40wt.% based on the total amounts of component having a salami structure and (B) 0.5-5 pts.wt., preferably 1-3.5 pts.wt. polyorganosiloxane having 500-100,000, preferably 800-80,000 centistokes viscosity at 25 deg.C. |
