Abstract

The method for producing starch esters using vinyl ester as the esterifying agent; The present invention is characterized in that a vinyl ester where the ester residue has from 2 to 18 carbon atoms is used as the esterifying agent and this is reacted with a starch in a non-aqueous organic solvent in presence of an esterification catalyst. This starch ester composition has a high degree of substitution, high molecular weight, high water proof and biodegradability.
This starch ester composition may be shaped into the moldings having much higher mechanical strength and better physical properties.
