  • Decomposition of ethylenically unsaturated carboxylic esters
    Patent number: 5422269
    Abstract: Residual levels of monomeric ethylenically unsaturated carboxylic acid esters such as alkyl acrylate and methacrylates, especially ethyl, butyl and "iso-hexyl" acrylates and methacrylates, in surfactant stabilised dispersions of polymers of the monomer(s) such as latices or products formulated from latices, are reduced by treatment with a hydrolytic enzyme, particularly a lipase or esterase. The treatment reduces and can obviate the perceived bad odour of the dispersions arising from the presence of the monomers.
