RESIN COMPOSITION FOR CALENDER PROCESSING

摘要

PROBLEM TO BE SOLVED: To provide a resin composition for calender processing capable of forming a good surface appearance without generating dent on the surface of a sheet obtained by calendering and insuring good impact resistance and heat resistance. SOLUTION: The resin composition comprises 100 pts.wt. of an impact resistant polystyrene resin, 0.5-10 pts.wt. of a slipping agent, and 8-40 pts.wt. of MBS copolymer (methyl methacrylate-butadiene rubber-styrene copolymer) fine particles having an average particle diameter of 1200 angstrom or more.
