Disclosed is a flame-retardant polyester resin composition comprising (1) a reinforced resin composition obtained by melt blending (A) a polyethylene terephthalate resin, (B) glass fibers, a combination of (C) at least one flame retarder having a specified chemical structure and (D) hexabromobiphenyl ether used in specific proportions, (E) antimony trioxide and optionally (F) an inorganic filler; and (2) (G) at least one ester compound subsequently added to the reinforced resin composition, the ester compound being derived from pentaerythitol and a fatty acid. This flame-retardant polyester resin composition can yield molded articles having excellent mechanical properties and flame retardancy, and exhibits good releasability of the molded article and rapid feed into the molding machine at the time of molding. |
