PURPOSE:To provide a rubber-modified styrenic resin composition having excellent thermal stability and slidability and free of the generation of black streaks when molded by comprising a rubber-modified styrenic resin, an organopolysiloxane and an alcoholic OH group-containing compound. CONSTITUTION:A rubber-modified styrenic resin composition having excellent slidability comprises (A) 100 pts.wt. of a rubber-modified styrenic resin prepared by graft-copolymerizing vinylic monomers mainly comprising a styrenic monomer to a rubbery polymer and having a rubbery polymer content of 3-20wt.%, (B) 0.5-1.5 pts.wt., preferably 0.75-1.0 pt.wt., (as silicon content) of an organopolysiloxane, preferably polydimethylsiloxane, having a kinematic viscosity of preferably 5000-50000 centistokes at 25 deg.C and (C) 0.05-2 pts.wt., preferably 0.1-1 pt.wt., of a compound (e.g. stearyl alcohol) having one or more alcoholic OH groups in the molecule. |
