POLYESTER RESIN COMPOSITION AND MOLDED BODY CONTAINING THIS RESIN COMPOSITION

摘要

The purpose of the present invention is to inhibit changes over time in the mechanical properties of an obtained molded article by improving slowness of crystallization, which is a drawback in polyhydroxyalkanoates that exhibit slow crystallization, thereby improving processability when carrying out molding such as injection molding or blow molding, and improving processing speed and obtaining finely dividing crystals. Provided is a polyester resin composition that contains a polyhydroxyalkanoate and pentaerythritol.
