Abstract POLYMERIZATION IS INITIATED ELECTROLYTICALLY BY PASSING A CURRENT THROUGH AN ELECTROCHEMICAL SYSTEM COMPRISED OF A METALLIC ANODE, A CATHODE, THE ANODE AND CATHODE BEING IMMERSED IN AN ELECTROLYTIC SOLUTION CONTAINING AN ELECTROLYTE AND POLYMERIZABLE MONOMERS, THE ELECTROLYTIC SOLUTION BEING INERT TOWARD SAID ANODE ON MERE CONTACT THEREWITH, BUT SOLUBILIZING THE ANODE WHEN AN ELECTRIC CURRENT IS PASSED. THE METAL IONS FORMED ON SOLUBILIZATION OF THE ANODE UPON ELECTROLYSIS ARE OXIDIZED WITH A COMPOUND WHICH FORMS FREE RADICALS, INITIATING POLYMERIZATION.
