Polyester resin composition.

摘要

A polyester resin composition of improved heat-resistant flexibility comprises: (A) a polyester copolymer prepared by the polycondensation of a component (a) mainly comprising an aromatic dicarboxylic acid or an ester-forming derivative thereof, with both a component (b) mainly comprising an aliphatic glycol, and a branch-forming component (c), wherein the component (c) is contained in an amount of 0.001 to 1.0 mole % based on the component (a), and (B) 0.1 to 10% by weight (based on the total amount of the composition) of a bisoxazoline compound. e
