Patent ID: 8163848

Claim:
A composition comprising or produced from, based on the total weight of the composition, about 40 to about 94% of poly(hydroxyalkanoic acid), about 3 to about 30% of an impact modifier, and about 3 to about 30% of an ion conductive polymer wherein the impact modifier is an ethylene copolymer derived from copolymerizing ethylene, carbon monoxide, and a comonomer selected from the group consisting of glycidyl (meth)acrylate, alkyl (meth)acrylate, vinyl ester, and combinations thereof; and the ion conductive polymer is selected from the group consisting of polyamide/polyether block amide, polyether block amide, polyether ester amide, or combinations of two or more thereof, each comprising 10 to 5000 ppm, based on the weight of the ion conductive polymer of an alkali metal compound, alkaline earth metal compound, salt of the alkali metal compound, or salt of the alkali earth metal compound.
