PURPOSE:To obtain a resin compsn. excellent in practical performance and antistatic properties by compounding a styrene resin, polyethylene oxide, a specific copolymer, a (meth)acrylic ester copolymer, and a specific surfactant. CONSTITUTION:A resin compsn. is prepd. by compounding 100 pts.wt. styrene resin, 3-35 pts.wt. polyethylene oxide having a viscosity-average mol.wt. of 15,000-1,5000,000, 0.1-10 pts.wt. styrene-acrylonitrile-hydroxyalkyl acrylate copolymer and/or styrene-acrylonitrile-hydroxyalkyl methacrylate copolymer, 4-100 pts.wt. (meth)acrylic ester copolymer, and a surfactant comprising a sulfonate of the formula (wherein R<1> and R<2> are each H or 12C or lower alkyl; and X is an alkali metal) or an alkyl sulfate seat of the formula, R<3>-OSO3M in an amt. of the surfactant of 0.4-5wt.% of the sum of the foregoing polymers. |
