POLYESTER RESIN COMPOSITION, MANUFACTURING METHOD THEREFOR, AND CAMERA MODULE CONTAINING SAID POLYESTER RESIN COMPOSITION

摘要

The purpose of the present invention is to provide a polyester resin with improved mechanical properties, molding performance, and, preferably, fire retardancy. This polyester resin composition contains the following: a polyester resin (A) that has a melting point or glass transition temperature of at least 250°C; a thermoplastic resin (B) that has an olefin-derived constitutional unit and an aromatic hydrocarbon structure and has an intrinsic viscosity ([&eegr;]), as measured in decalin at 135°C, of 0.04 to 1.0 dl/g; and a copolymer (C) that has an olefin-derived constitutional unit, an α,&bgr;-unsaturated-carboxylic-ester-derived constitutional unit, and a cyclic oxy-hydrocarbon structure.
