Polyester resin composition and polyester resin molded article

Abstract

This invention provides a polyester resin composition comprising an aromatic polyester resin. The molded body obtained from this polyester resin composition exhibits excellent heat resistance, suppressed deformation, and excellent impact resistance. Furthermore, a polyester resin molded body obtained by molding this polyester resin composition is provided, exhibiting excellent heat resistance, suppressed deformation, and excellent impact resistance. The polyester resin composition of an embodiment of this invention comprises an aromatic polyester resin (A), an organic crystallization promoter (B), and a polycarbodiimide compound (C). The polyester resin molded body obtained by injection molding using a mold capable of obtaining a molded body with a wall thickness of 2 mm at a mold temperature of 30°C has a crystallinity of 50% or more.
