Abstract:
A semi-crystalline film containing polylactide polymer composition, said polylactide polymer composition comprising:(i) a plurality of poly(lactide) polymer chains, said plurality having a number average molecular weight of from about 40,000 to about 250,000;(ii) residual lactide, if present at all, present in a concentration of less than about 0.5% by weight; and(iii) residual polymerization catalyst, if present at all, present in a concentration of less than about 0.7 milliequivalents of catalyst per kg of polylactide polymer;wherein the semi-crystalline film exhibits a net melting endotherm of greater than about 10 J/gm of polylactide when analyzed by a differential scanning calorimeter.
