| abstract |
Residual levels of monomeric ethylenically unsaturated carboxylic acid esters such as alkyl acrylates 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. |
