Abstract:
1. An anaerobically compostable hydrocarbon polymer composition comprising a hydrocarbon polymer selected from the group consisting of a vinyl halide polymer, vinyl acetate polymer, and an olefin polymer, and copolymers or blends thereof, and a monomeric adduct of an organotitanate or an organozirconate as a prodegradant in relative amounts to render the polymer composition anaerobically compostable under ASTM D-5526-94 conditions, and wherein said adduct is defined by the formula where X is a phosphate, nitrate or sulfonate group, R is a hydrocarbon radical or substituted hydrocarbon radical and 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 dimethvlaminoethylmethacrylate, methyl dimethlaminopropyl 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.
