POLYCARBONATE RESIN COMPOSITION WITH IMPROVED COLORABILITY, SHOCK RESISTANCE, AND SCRATCH RESISTANCE BY ADDING A DENATURED ACRYLATE COPOLYMER AND A RUBBER-MODIFIED AROMATIC VINYL-BASED COPOLYMER TO A POLYCARBONATE RESIN

摘要

PURPOSE: A polycarbonate resin composition has excellent colorability, shock resistance, and scratch resistance.;CONSTITUTION: A polycarbonate resin composition comprises a polycarbonate resin, a denatured acrylate copolymer, a rubber-modified aromatic vinyl-acrulonitrile graft copolymer, a PBT(PolyButylene Terephthalate) resin, and a siloxane-polyester copolymer. The denatured acrylate copolymer comprises 'a unit derived from acrylate or methacrylate including an alicyclic structure or an aromatic hydrocarbon group'. An impact strength of the polycarbonate resin composition measured by notch izod based on ASTM D256 is 10-65 kgf·cm/cm.;COPYRIGHT KIPO 2013
