Abstract
Poly(lactic acid) polymer compositions each contain an appropriate poly(lactic acid) polymer and a suitable plasticizer having a polyether and/or polyester segment in combination. The compositions 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 are useful as formed plastics such as films.
