Patent ID: 7666946

Claim:
A biopolymer composition comprising: a) 85 to 99.9 weight percent of one or more biopolymers, wherein said biopolymer comprises at least one synthetic biopolymer selected from the group consisting of polylactide and polyhydroxy butrate, and wherein said polylactide and/or polyhydroxy butyrate comprise 30-99.9 weight percent of the total biopolymer composition; and b) 0.1 to 15 weight percent of one or more acrylic copolymers having a weight average molecular weight of greater than 1,000,000, wherein said acrylic copolymer consists of 60 percent or more of an acrylic and/or methacrylic monomer units, and 0-40 percent of one or more other ethylenically unsaturated monomers selected from the group consisting of styrene, alpha-methyl styrene, butadiene, vinyl acetate, vinylidene fluorides, vinylidene chlorides, acrylonitrile, vinyl sulfone, vinyl sulfides, and vinyl suloxides.
