Abstract: A process for reducing the amount of residual monomer in aqueous polymerization emulsion by using a sequential polymerization steps, The first step consists in adding an emulsion, of vinyl ester of alkyl of C1 to C18 carboxylic acids, to water containing a radical initiator, the second step consists in adding further an emulsion of alkyl acrylate and/or methacrylate, and the third step consists in c) adding to polymeric emulsion, resulting of the steps a) and b), pure liquid acrylate or methacrylate with alkyl chain of C1 to C12.
