Abstract
A starch derivative which, when incorporated with no or only a little plasticizer, yields moldings having good flexibility, toughness, and water-relating properties for practical use comprises an esterified, polyvinyl ester-grafted starch derivative which is formed by esterifying starch and grafting starch with a polyvinyl ester. The polyvinyl ester is derived from one or more saturated or unsaturated aliphatic acids or aromatic carboxylic acids having 2 to 18 carbon atoms.
