Abstract:
1. A thermoplastic composition, comprising: (a) polyhydroxyalkanoate, (b) an effective amount of surface treated precipitated calcium carbonate to crystallize the polyhydroxyalkanoate at a temperature of higher than about 108° C., and wherein the precipitated calcium carbonate is represented by CAS No. 471-34-1 and has an aspect ratio of about 5.42 and a specific gravity of about 2.7, wherein the effective amount is not more than about 6 weight percent of the composition, and (c) an effective amount of a property-modifying additive selected from the group consisting of a thermal conductivity additive, an electrical conductivity additive, a sound dampening additive, an ionizing-radiation-opacity additive, an atomic-particle-moderating additive, and combinations thereof,
