A flame-resistant polybutylene terephthalate molding composition has vastly improved fatigue strength and improved melt flow by incorporating therein a halogenated epoxy flame retardant represented by the general formula: <IMAGE> (I) <IMAGE> +TR <IMAGE> wherein an n is the degree of polymerization and the halogenated epoxy resin has a molecular weight of at least about 20,000 to 40,000; X is a chlorine or bromine atom, and i is an integer of from 1-4. |
