Mitsutaka reflective aromatic polycarbonate resin composition

摘要

PROBLEM TO BE SOLVED: To provide a highly light-reflecting aromatic polycarbonate resin composition exhibiting not only excellent reflecting properties, mechanical strength causing no delamination and flow properties but also good heat resistance that comprises as a base material a polycarbonate resin having a titanium dioxide pigment incorporated therewith.;SOLUTION: The highly light-reflecting aromatic polycarbonate resin composition comprises 100 pts.wt. of the total of 60-99 pts.wt. of an aromatic polycarbonate resin (component A) and 1-40 pts.wt. of the titanium dioxide pigment (component B), and 0.05-30 pts.wt. of a flow modifier (component C), where the flow modifier (component C) is a copolymer (i) comprising, as a main constituting unit, a unit formed from a (meth)acrylate monomer (Ca) represented by a specific formula and an aromatic alkenyl compound monomer (Cb) and (ii) containing a chloroform-soluble component having a weight-average molecular weight of 10,000-200,000.;COPYRIGHT: (C)2006,JPO&NCIPI
