POLYESTER RESIN COMPOSITION, AND MOLDED ARTICLE COMPRISING SAID RESIN COMPOSITION

摘要

The purpose of the present invention is: to improve both delayed crystallization and brittleness which are disadvantageous properties of a polyhydroxyalkanoate, thereby improving processability in molding processing such as injection molding and therefore improving a processing speed and also imparting ductility to a molded article produced. An aliphatic polyester resin composition comprising a polyhydroxyalkanoate (A), an ethylene-(vinyl acetate) copolymer resin (B) and pentaerythritol (C), wherein the content ratio of vinyl acetate in the component (B) is 65 to 95 wt% and the components (A) are (B) dissolved in each other.
