(57) [Summary] [Structure] Phenolic hydroxyl group-containing organic sulfonates. 01 to 20 parts by weight of polyester resin (1 to 99 parts by weight) added before completion of polycondensation, polyester (99 parts by weight) Up to 1 part by weight). [Effect] Since the polyester composition of the present invention has a high crystallization rate, it has excellent moldability in a low temperature mold, and the resulting molded article has good mechanical properties, fluidity, hydrolysis resistance, and electrical properties. Since it has weather resistance, it is particularly useful as an electric / electronic component, an automobile component, a mechanical mechanism component, and the like. |
