Abstract
Disclosed is a flame retardant polycarbonate resin composition having an improved melt fluidity, which comprises (A) an aromatic polycarbonate having a weight average molecular weight of from 12,000 to 25,000, (B) a styrene-acrylonitrile-butyl acrylate copolymer having a butyl acrylate unit content of from 1 to 30% by weight, (C) a complex rubber graft copolymer obtained by a process comprising graft-polymerizing at least one graft-polymerizable monomer onto a complex rubber comprising a polyorganosiloxane and a polyalkyl (meth)acrylate, (D) a phosphoric ester, and (E) a tetrafluoroethylene polymer. The resin composition of the present invention not only has excellent melt fluidity, but is also excellent in flame retardancy, impact resistance and modulus of elasticity. The resin composition of the present invention can be advantageously used for producing various types of shaped articles (including those for use in office automation machines and in electric and electronic equipment), and is especially advantageous for producing small-thickness shaped articles.
