Patent ID: 7642301

Claim:
A composition comprising about 50 to about 99.5 wt % of a poly(hydroxyalkanoic acid), about 0.1 to about 40 wt % of an ethylene ester copolymer, and about 0.05 to about 5 wt % of an aliphatic carboxylic acid amide, based on the total weight of the composition, wherein the ethylene ester copolymer comprises (a) about 20 to about 95 wt % of copolymerized units of ethylene, (b) about 0.5 to about 25 wt % of copolymerized units of at least one ester of the formula CH 2 ═C(R 1 )CO 2 R 2 , wherein R 1 is hydrogen or an alkyl group having 1-6 carbon atoms, and R 2 is glycidyl, based on the total weight of the ethylene ester copolymer and (c) 0 to about 70 wt % of copolymerized units of at least one ester of the formula CH 2 ═C(R 3 )CO 2 R 4 , wherein R 3 is hydrogen or an alkyl group having 1 to 8 carbon atoms and R 4 is an alkyl group having 1 to 8 carbon atoms, based on the total weight of the ethylene ester copolymer.
