POLYCARBONATE RESIN COMPOSITION AND RESIN MOLDED ARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a polycarbonate resin composition having both of high surface hardness and good transparency.SOLUTION: A polycarbonate resin composition contains (A) a polycarbonate resin, (B) an acrylic modifier and (C) a graft copolymer. The content of the (B) acrylic modifier is 5 to 60 pts.wt. and the content of the (C) graft copolymer is 0.5 to 20 pts.wt. based on 100 pts.wt. of the total content of the (A) polycarbonate resin and the (B) acrylic modifier. The (C) graft copolymer is constituted by 50 to 80 wt.% of polycarbonate and 20 to 50 wt.% of a polymethacrylic methyl copolymer and the polycarbonate is a main chain and the polymethacrylic methyl copolymer is a side chain. The polymethacrylic methyl copolymer contains 10 wt.% or more of methyl methacrylate.SELECTED DRAWING: None
