TRANSPARENT FLAME-RETARDANT AROMATIC POLYCARBONATE RESIN COMPOSITION, AND MOLDED PRODUCT THEREOF

摘要

Disclosed is a polycarbonate resin composition which comprises (A) a polycarbonate resin component comprising (A-1) 10 to 90 mass% of an aromatic polycarbonate resin produced by using a dihydroxybiphenyl as a part of a divalent phenol component, (A-2) 10 to 90 mass% of an aromatic polycarbonate-polyorganosiloxane copolymer, and (A-3) 0 to 80 mass% of an aromatic polycarbonate resin which is different from the components (A-1) and (A-2).  The polycarbonate resin composition is improved in flame retardancy while maintaining transparency.  Also disclosed is a molded article of the polycarbonate resin composition.  In the flame-retardant polycarbonate resin composition, the component (A) preferably contains a polyorganosiloxane at a ratio of 0.3 to 1.6 mass% and may additionally contain (B) an organic metal salt in an amount of 0.01 to 1 part by mass relative to 100 parts by mass of the component (A).
