Patent ID: 8829112

Claim:
A composition comprising or produced from poly(hydroxyalkanoic acid), a first modifier, and a second modifier wherein the composition does not comprise a methacrylic resin containing repeat unit derived from methyl methacrylate; the poly(hydroxyalkanoic acid) comprises repeat units derived from a hydroxyalkanoic acid having 2-10 carbon atoms; the first modifier is a polymer that is incompatible with the poly(hydroxyalkanoic acid) and is not an acid-containing polymer or acid-generating polymer; the first modifier is selected from the group consisting of ethylene copolymer, copolyetherester, epoxidized oil, acrylonitrile styrene copolymer, a styrene-containing polymer, aromatic polyester, aliphatic-aromatic polyester, ethylene propylene diene monomer rubber, and combinations of two or more thereof; the ethylene copolymer comprises repeat units derived from ethylene and a comonomer selected from the group consisting of methyl acrylate, ethyl acrylate, propyl acrylate, butyl acrylate, CO, glycidyl acrylate, glycidyl methacrylate, glycidyl acrylate, butyl acrylate glycidyl methacrylate, and combinations of two or more thereof; the copolyetherester comprises a multiplicity of recurring long-chain ester including the polyether segments units and short-chain ester units joined head-to-tail through ester linkages; and the second modifier includes polycarbodiimide, carbodiimide, diimide compound, or combinations thereof.
