ABSTRACT:
A film having a net endotherm greater than about 10 joules per gram of polymer that contains chains including lactic acid residuals; said film further comprising; a) a melt stable polymer composition comprising at least 5% by weight of a melt stable first polymer component with lactic acid residuals b) said first polymer having a number average molecular weight of at least 40,000 and no greater than 300,000 and c) said first melt stable polymer composition having a lactide concentration of less than about 2% by weight of melt stable polymer including polymer chains with lactic acid residuals. A process for preparing a film having a net endotherm greater than about 10 joules per gram of polymer that contains chains including lactic acid residuals is also disclosed.
