Patent ID: 7939582

Claim:
An anaerobically compostable vinyl acetate polymer composition comprising a vinyl acetate polymer and a monomeric adduct of an organotitanate or organozirconate as a prodegradant in relative amounts to render the vinyl acetate polymer composition anaerobically compostable under ASTM D-5526-94 conditions, wherein said adduct is defined by the formula: organotitanate or zirconate —P═O(OH) salt-forming group-R—C═C-activating group, wherein R is a hydrocarbon radical or substituted hydrocarbon radical and the activating group has a C═O, —CN, oxygen, nitrogen, sulfur, or an aromatic ring conjugated with the C═C to activate the carbon-carbon double bond, wherein the substituent of the substituted hydrocarbon radical is selected from the group consisting of an ether, thioether, ester, thioester, and amide wherein the monomeric adduct is an adduct of a monomer selected from the group consisting of ethyl dimethylaminoethylmethacrylate, methyl dimethylaminopropyl acrylate, 2-morpholine-N-ethyl acrylamide, 2-piperidinyl-N-ethyl acrylonitrile, 2-dimethylaminoethyl acrolein, dimethylaminoethyl vinyl ether, dimethylaminoethyl vinyl thioether, 4-dimethylaminomethyl styrene, allyl 3-dimethylamino propionate, methallyl 3-dimethylamino propionate, thioallyl 3-dimethylamino propionate, dimethylaminomethyl acrylate, and dimethylaminomethylacrylamide.
