The electroinduced and chemical dispersion polymerization of methyl methacrylate was performed in aqueous methanol solution (water/methyl alcohol ratio 50/50 by wt%) in the presence of poly(vinyl pyrrolidone) as a stabilizer with ceric sulfate as an initiator. The effects of various polymerization parameters, for example concentrations of recipe ingredients, temperature, potential, and duration, on polymerization yield were examined. In all cases higher yield was obtained with the electrochemical polymerization procedure. Initiation rates of polymerization processes, thermal properties of polymers, interaction of initiator with monomer and stabilizer were investigated in detail. Possible structure of polymer is proposed, and a tentative polymerization mechanism is suggested.
