Transformation of Aqueous Methyl Methacrylate Solution Into Stable Monodisperse Latex via Polymerization Initiated by Hydroquinone-Potassium Persulfate System

The aim of this work was to identify the possibilities of synthesizing stable latex with a narrow particle distribution by homogeneous polymerization in an aqueous solution of methyl methacrylate. The polymerization of methyl methacrylate was first carried out under static conditions in an aqueous solution of the hydroquinone-potassium persulfate oxidation-reduction system. It was assumed that semiquinone anion radicals formed at the intermediate stage of hydroquinone oxidation can participate in the reactions of termination of growing radicals and by changing the molecular parameters of polymer molecules, affect the process of formation of latex particles. The article presents the results of the study of the colloidal parameters of the obtained latex, which show that the selected polymerization conditions allow reproducibly synthesizing monodisperse stable latex.
