ABSTRACT:
The invention is directed toward melt-processable lactide polymer compositions, processes for manufacturing these compositions, and articles made from these compositions. The compositions include a first phase, which contains a polylactide-based polymer, and a second phase which includes elastomer. The elastomer is present in an amount sufficient to provide a polymer composition having an impact resistance of at least about 0.7 ft-lb/in. after the melt-processable polymer composition has been injection molded into bars and tested according to ASTM D256 (1993) method C. Preferably, the compositions also include a reactive compatibilizing agent. Methods of making these compositions and articles made from these compositions are also disclosed.
