Abstract
A thermoplastic compound is disclosed, comprising polyhydroxyalkanoate and macrocyclic poly(alkylene dicarboxylate) oligomer. Optionally the compound also includes additional polymers and functional additives to modify physical properties of the compound. Molded or extruded plastic articles can be made from the compound. The compound is ductile, in comparison to the polyhydroxyalkanoate without the macrocyclic poly(alkylene dicarboxylate) oligomer.
