WIPO Patent Application WO/1996/027617
Kind Code:
A1
Abstract:
A modified starch which has been esterified and grafted with a polyvinyl ester and is usable as a biodegradable molding material. The esterifying acid is at least one member selected from among saturated and unsaturated C2-18 fatty acids and aromatic carboxylic acids. The acid of the grafting vinyl ester is at least one member selected from among saturated and unsaturated C2-18 fatty acids and aromatic carboxylic acids.
