PROBLEM TO BE SOLVED: To obtain a resin composition which can be calendered with increased peelability from the surroundings of the bank and the hot rollers without adverse effect on its excellent performance by admixing a specific copolymer to a rubber-modified thermoplastic resin. SOLUTION: This resin composition is prepared by formulating (A) 0.1-15 pts.wt. of a copolymer from 10-90wt.% of methyl methacrylate units, 5-60wt.% of an alkyl acrylate units, preferably butyl acrylate and 0-50wt.% of monomer units copolymerizable with these monomers to 100 pts.wt. of a rubber-modified thermoplastic resin having (B) 10-90 pts.wt. of a graft rubber copolymer prepared by grafting 10-45 pts.wt. of a vinyl cyanide, preferably acrylonitrile and 55-90 pts.wt. of an aromatic vinyl compound, preferably styrene onto 25-75 pts.wt. of a rubber (co)polymer, preferably polybutadiene rubber and (C) 10-90 pts.wt. of a copolymer having 10-45wt.% of a vinyl cyanide units and 55-90wt.% of an aromatic vinyl units. |
