    Notes: Ethyl methacrylate is polymerized by electroinitiation in methanol-electrolyte mixtures in which the monomer is soluble whereas the polymer obtained is insoluble. A technique of changing the polarity of the electrodes is used. With this technique a polymer of high molecular weight can be obtained. The relationships between molecular weight and monomer concentration, current densities, and time of the reaction as well as the yield as a function of current density, time of the reaction and initial monomer concentration are given. A free-radical mechanism is proposed for the reaction.

    Notes: Methyl, ethyl, and n-butyl acrylates and methacrylates are polymerized by electroinitiation in methanol-, ethanol-, and n-propanol-electrolyte mixtures in which the monomers are soluble whereas the polymers obtained are insoluble. The technique of changing the polarity of the electrodes described earlier was used. The relationships between molecular weights and polymer yields as function of current density, initial monomer concentration and dielectric constant of the solvent are described. A kinetic scheme for the initiation, propagation, and termination is given.
