Poly(lactid acid) polymer composition, formed plastics thereof and film

摘要

Poly(lactic acid) polymer compositions of the invention each contain an appropriate poly(lactic acid) polymer and a suitable plasticizer having a polyether and/or polyester segment in combination, exhibit satisfactory flexibility and show very small amount of the evaporation, migration and extraction (bleedout) of the plasticizer and losing transparency upon heating. The poly(lactic acid) polymer compositions of the invention are useful as formed plastics such as films.
