    Abstract: The present invention relates to a method comprising the steps of a) contacting under emulsion polymerization conditions vinyl acetate; a cyclic ketene acetal monomer; and a monoethylenically unsaturated acid monomer or a salt thereof; to form an aqueous dispersion of copolymer particles comprising structural units of vinyl acetate, the cyclic ketene acetal, and the 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 method 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 is a composition comprising a solution or a dispersion of polymer particles, a sorbate ester or sorbamide curing agent, and a cure modulating additive for the curing agent. The curing agent is a sorbic acid ester or a sorbamide and the cure modulating agent is a reagent capable of accelerating or attenuating the rate of cure of the curing agent. The control of cure kinetics is important for speeding up cure rates where rates are too slow or by reducing cure rates where curing too rapidly results in undesirable color formation.

    Abstract translation: 本发明是一种组合物，其包含聚合物颗粒，山梨酸酯或山梨酰胺固化剂的溶液或分散体，以及用于固化剂的固化调节添加剂。 固化剂是山梨酸酯或山梨酰胺，固化调节剂是能够加速或减弱固化剂固化速度的试剂。 固化动力学的控制对于加快速率太慢的固化速率或通过降低固化速度来说重要，其中固化太快导致不期望的颜色形成。
