Abstract: The present invention relates to a composition comprising an aqueous dispersion of copolymer particles comprising structural units of vinyl acetate, a cyclic ketene acetal monomer, and a monoethylenically unsaturated acid monomer, or a salt thereof; wherein the cyclic ketene acetal monomer is characterized by following structure: where n and the R groups are as defined herein. The composition of the present invention provides a water-borne dispersion that is substantially free of volatile organic solvents and that provides a readily degradable polymer that is useful, for example, in the manufacture of biodegradable packaging products.

Abstract: The present invention provides telomeric copolymers of acrylic and methacrylic acid which further comprise an olefin polymerization residue and have one or more phosphorus acid groups wherein the phosphorus acid group comprises one or more phosphorus atom in the +1 oxidation state or in the +3 oxidation state, or both. In addition the present invention provides methods of making the telomeric copolymers comprising aqueous solution copolymerizing a monomer mixture comprising acrylic acid and methacrylic acid in the presence of a phosphorus acid group containing reactant having a phosphorus atom in the +1 oxidation state, and thermally treating the resulting telomeric copolymer at 175° C. or higher for a sufficient time to decarboxylate the copolymer.
