A flame-retardant polycarbonate resin composition which comprises 100 parts by weight of a polycarbonate resin (A), 0.01 to 10.0 parts by weight of a divalent metal sulfate (B), and 0.01 to 8.0 parts by weight of a silicone compound (C) wherein the backbone chain has a branched structure and the constituent organic functional groups consist of aromatic groups or of aromatic groups and hydrocarbon groups (except aromatic groups); and moldings of the flame-retardant polycarbonate resin composition. The flame-retardant polycarbonate resin composition may further contain 0.01 to 2.0 parts by weight of an organometallic salt compound (D) and/or 0.05 to 5.0 parts by weight of a fiber-forming type fluorine-containing polymer (E). The flame-retardant polycarbonate resin composition exhibits extremely excellent flame retardance, though no halogen- or phosphorus-containing conventional flame retardants are used in the resin composition. Therefore, the resin composition is free from the risk of producing, when burning, halogen- or phosphorus- containing gas resulting from such conventional flame retardants, thus being also environmentally excellent. |
