BLENDS OF STARCH AND ALIPHATIC-AROMATIC BASED POLYESTER RESINS

摘要

A blend of starch and a thermoplastic aliphatic-aromatic copolyester resin, at a specific gravity of greater than 1.0. In method form, the invention comprises supplying an aromatic-aliphatic based polyester, supplying starch and mixing the aromatic-aliphatic based polyester with the starch and introducing the mixture to a melt processing apparatus wherein the aromatic- aliphatic based polyester and starch are mixed and molded or extruded into a desired shape.
