Abstract
A flame retardant antistatic polyester resin composition having excellent flame resistance, antistatic properties, mechanical strength and heat resistance, which includes a thermoplastic polyester and, per 100 parts by weight of the thermoplastic, 1 to 35 parts by weight of a bromine-containing flame retardant, 0.1 to 5 parts by weight of an antimony compound, 3 to 12 parts by weight of a conductive carbon black, 0.05 to 30 parts by weight of a low molecular weight polyester compound and 0.1 to 5 parts by weight of a metal salt of an ionic hydrocarbon copolymer. The resin composition may further contain a reinforcing filler, a crystallizing accelerator or a polyfunctional compound reactive with either or both of hydroxyl groups and carboxyl groups.
