Abstract
An object is to increase crystallization speed, which is a drawback of polyhydroxyalkanoate, to improve processability in processing such as injection molding or blow molding and increase the speed of processing and is, in addition, to refine the crystal of polyhydroxyalkanoate to suppress a change of mechanical properties with passage of time of a resulting molded article. Disclosed herein is a polyester resin composition containing polyhydroxyalkanoate and pentaerythritol.
