PROBLEM TO BE SOLVED: To obtain a resin composition capable of being calendered into a sheet excellent in transparency, surface smoothness and nonproblematic in e.g. the formation of flow marks by mixing an ABS resin with an acrylic acid resin and an organotin compound in a specified mixing ratio. SOLUTION: This composition comprises 100 pts.wt. ABS resin, 0.5-6.0 pts.wt. acrylic acid resin, 0.2-5.0 pts.wt. organotin compound, and 0.2-3 pts.wt. organic phosphoric ester or 0.2-5 pts.wt. polyhydric alcohol/fatty acid ester. The ABS resin is desirably a transparent one such as acrylonitrile/butadiene/styrene/methyl methacrylate resin copolymer resin, a methyl methacrylate/butadiene/styrene copolymer resin, or the like. The acrylic acid resin is exemplified by a polyacrylic acid or an acrylic acid/methacrylic acid copolymer each having a weight-average molecular weight of 2.0×105 to 4.0×105. The organotin compound used is exemplified by stannous stearate, stannous oleate, or di-n-octyltin dilaurate. |
