  • Patent number: 9828510
    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.

  • Publication number: 20170305832
    Abstract: The present invention is a process for preparing a sorbate ester comprising the steps of: a) contacting together in a reaction vessel a first organic solvent, sorbic acid, a catalytic amount of TiC14, an anti-oxidant, and an alkylene oxide under conditions sufficient to form a mixture of the sorbate ester and residual water-soluble impurities; then b) separating the sorbate ester from the residual water-soluble impurities by washing. Sorbate esters can be prepared in an efficient and cost-effective manner by the process of the present invention.

  • Publication number: 20170305831
    Abstract: The present invention is a process for preparing a hydroxyalkyl sorbate comprising the steps of of: a) contacting together in a reaction vessel a solvent, sorbic acid, a transition metal halide catalyst, an anti-oxidant, and an alkylene oxide under conditions sufficient to form the hydroxyalkyl sorbate; b) removing the solvent in vacuo, wherein the anti-oxidant is characterized by the following formula or a carboxylic acid salt thereof: wherein Y, x, and R1 are defined herein. The process of the present invention provides a convenient way of preparing hydroxyalkyl sorbates in high yield and purity without complicated workup steps.
