BIODEGRADABLE POLYESTER RESIN COMPOSITION

摘要

[PROBLEMS] To provide a biodegradable polyester resin composition that even through milling process, can realize excellent antistatic property and surface smoothness while retaining molecular weights without detriment to the resin appearance. [MEANS FOR SOLVING PROBLEMS] There is provided a biodegradable polyester resin composition comprising 0.05 to 10.0 wt.% of surfactant of boric ester having one or more C₈-C₂₄ hydrophobic groups (product of reaction between boric acid and a compound obtained by esterification of a polyhydric alcohol with a higher fatty acid, a salt of the reaction product, product obtained by reacting a boric ester of polyhydric alcohol with a higher fatty acid, etc.).
