Abstract
A composition includes a polymer having a poly-lactide and at least one compound of formula (I), where L1 is C1-8alkylene or C3-6cycloalkylene; L2 is C1-6alkylene; L3 is C1-6alkylene; L4 is C1-6alkylene; L5 is C1-6alkylene; n is an integer selected from 1, 2, 3 or 4; m is an integer selected from 1, 2, 3 or 4; R1 is H; or C1-6alkyl; R2 is H; or C1-6alkyl. The poly-lactide is poly-L-lactide comprising a content of D isomer of at least 10% by weight based on the total weight of the poly-L-lactide; poly-D-lactide comprising a content of L isomer of at least 10% by weight based on the total weight of the poly-D-lactide; poly-DL-lactide; poly(meso-lactide); or mixtures thereof.
