Abstract
The present invention relates to a process for producing a polyester resin composition, including the step of mixing a polyester resin (A), an aromatic carbodiimide (B) and an aliphatic polycarbodiimide (C) at a temperature not lower than a melting temperature of the polyester resin, in which the polyester resin (A) and the aromatic carbodiimide (B) are mixed in the presence of the aliphatic polycarbodiimide (C).
