SCRATCH-RESISTANT POLYCARBONATE RESIN COMPOSITION WITH THE EXCELLENT BALANCE OF FLAME RESISTANCE, TRANSPARENCY, COLORING PROPERTY AND MECHANICAL PROPERTY AND MOLDED PRODUCT THEREOF

摘要

PURPOSE: A polycarbonate resin composition is provided to apply in the parts of electronic products as the composition has heat resistance, flame resistance, scratch resistacne, mechanical property and transparency.;CONSTITUTION: A scratch resistant polycarbonate resin composition contains (A) 50-99 weight% of polycarbonate resin; (B) 1-50 weight% of (meth)acrylic copolymer containing a biphenyl group with 1.495-1.640 of refractive index; (C) 0-30 parts by weight of a rubber-modified vinyl graft copolymer resin; and (D) 0-30 parts by weight of phosphoric flame retardant per 100.0 parts by weight of the polycarbonate resin composition. The (meth)acrylate copolymer(B) has a glass transition temperature ranged 90-150 degreeC and a weight average molecular weight ranged 3,000-300,000.;COPYRIGHT KIPO 2013
