ABSTRACT:
A flame-resisting polycarbonate resin composition is disclosed, comprising (a) 100 parts by weight of an aromatic polycarbonate resin comprising (i) a copolymer of a halogenated 4,4'-dihydroxydiphenylalkane and a non-halogenated 4,4'-dihydroxydiphenylalkane or (ii) the copolymer (i) or a homopolymer of the non-halogenated 4,4'-dihydroxydiphenylalkane having incorporated therein a homo-oligomer of the halogenated 4,4'-dihydroxydiphenylalkane and/or a co-oligomer of the halogenated 4,4'-dihydroxydiphenylalkane and the non-halogenated 4,4'-dihydroxydiphenylalkane, (b) 0.001 to 5.0 parts by weight of an organic potassium phosphate, (c) 0.001 to 0.5 parts by weight of an phosphorous ester compound, and (d) 0 to 0.5 part by weight of an organosilicone compound. The resin composition has an improved viscosity characteristic and is, therefore, prevented from dripping during combustion, and does not suffer change in hue or reduction in molecular weight during molding.
