Abstract: A flame retardant thermoplastic resin composition includes (a) a polycarbonate resin, (b) an impact modifier, and (c) resorcinol bis(diphenyl phosphate). The impact modifier includes (b1) a large rubber particle-modified vinyl graft copolymer wherein the rubber particle has an average particle diameter of about 0.3 to about 0.7 ?m, and (b2) a small rubber particle-modified graft copolymer wherein the rubber particle has an average particle diameter of about 0.05 to about 0.27 ?m. The flame retardant thermoplastic resin composition can have excellent flowability, mold formability, flame retardancy, impact strength, and gloss characteristics.

Abstract: A thermoplastic resin composition includes a polycarbonate resin/impact modifier system, a polystyrene resin having a predetermined molecular weight, and a phosphorus flame retardant. The impact modifier includes a particular rubber particle size and is formed of particular monomers. The composition can exhibit improved flame retardancy, impact resistance, fluidity, and appearance.

Abstract: The present invention discloses a polycarbonate resin composition which includes a polycarbonate resin (A), a polycarbonate-polysiloxane copolymer (B), and a siloxane copolyester (C), wherein the siloxane copolyester (C) is present in an amount of about 0.1 to about 6 wt % based on 100 wt % of a base resin including the polycarbonate resin (A), polycarbonate-polysiloxane copolymer (B), and siloxane copolyester (C). The composition can have excellent mold release properties and appearance.

Abstract: The thermoplastic resin composition of the present invention comprises: about 100 parts by weight of a base resin comprising (A) about 5 to about 40% by weight of a rubber modified aromatic vinyl based copolymer resin, (B) about 30 to about 90% by weight of a polycarbonate resin, and (C) about 1 to about 50% by weight of a noncrystalline polyester resin; and (D) about 5 to about 30 parts by weight of an aromatic phosphate ester based compound.
