Title:

METHOD OF IMPARTING ANTISTATIC PROPERTY TO BIODEGRADABLE POLYESTER RESIN COMPOSITION AND PRODUCTS MADE OF THE RESIN COMPOSITION

Document Type and Number:

WIPO Patent Application WO/2004/069930

Kind Code:

A1

Abstract:

A method of imparting antistatic properties to a biodegradable polyester polymer or resin, especially polybutylene succinate or the like. The method enables a biodegradable polyester resin composition to have high antistatic properties and persistence thereof, be prevented from suffering bleeding, and be highly safe and reduced in the burden to be imposed on the environment. Also provided are a film, sheet, and molded article. In the method, which is for imparting antistatic properties to a biodegradable polyester resin composition comprising a biodegradable polyester resin and incorporated therein a diglycerol/fatty acid ester, the constituent fatty acid of the diglycerol/fatty acid ester has 16 to 18 carbon atoms, the diglycerol/fatty acid ester has an HLB of 4 to 8, and the content of the diglycerol/fatty acid ester is 0.2 wt.% or higher and lower than 2.0 wt.%.
