摘要： There is disclosed a flame retardative polycarbonate resin composition which comprises 100 parts by weight of an aromatic polycarbonate resin (A), 0.01 to 0.5 part by weight of an alkali/or alkaline-earth metal salt of a perfluoroalkanesulfonic acid (B), 0.03 to 5 parts by weight of an organopolysiloxane containing organoxysilyl group bonded to a silicon atom through a divalent hydrocarbon group (C), and optionally 5 to 120 parts by weight of an inorganic filler. The above composition has excellent flame retardancy capable of preventing dripping thereof at the time of combustion of a thin-walled material made from the highly fluidized composition while maintaining the dimensional stability and the mechanical properties such as impact resistance that are inherent in polycarbonate.
