POLYCARBONATE RESIN COMPOSITION WITH EXCELLENT MAR RESISTANCE AND SCRATCH RESISTANCE

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.
