POLYESTER RESIN MOLDING, AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a polyester resin molding containing polyhydroxyalkanoate excellent in mechanical characteristics such as biodegradability and elongation, which are characteristics inherent to a polyester resin; and to provide a method for producing the same.SOLUTION: There is provided a method for producing a polyester resin molding that is a molding containing polyhydroxyalkanoate (PHA) and in which fine particles (PHA fine particles) of the PHA are deposited on a part of the surface of the molding; preferably, a method for producing a polyester resin molding in which PHA fine particles having an average particle diameter of 0.01-300 μm are dispersed with a concentration of 0.01-10 wt.% when a medium is liquid or with a concentration of 0.1-100 mg/cmwhen the medium is gas; and a method for obtaining a polyester resin molding which can prevent blocking in the production and contains a polyester resin molding containing PHA excellent in mechanical properties such as tensile elongation.SELECTED DRAWING: None
