PROCESS FOR MAKING STARCH-RESIN COPOLYMER

摘要

A process for making a starch-resin copolymer is described, the process comprising: mixing at least one of a dicarboxylic acid and a dicarboxylic acid anhydride with a starch to yield a starch mixture; adding a liquid mixture including water and a polyol to the starch mixture to produce a functionalized starch; and mixing the functionalized starch with a resin to produce the starch-resin copolymer, wherein the starch used in the process has a low moisture content in comparison with the moisture content of starch used in current processes. Starch-resin copolymers produced by the present process can be biodegradable and compostable.
