Abstract
Abstract An improved process for the production and recovery of a processable electropolymerized conductive polymer is disclosed whereby there is used as the anode in the electropolymerization of an electropolymerizable monomer, an electrically conductive polymeric anode which is processed from a processable polymer comprising an oxidatively polymerized polymer having cationic character in affiliation with polymeric particles having anionic surface character, and whereby both the anode and the desired electropolymerized product formed thereon by electropolymerization are recovered by simultaneous processing of the anode and electropolymerized product thereon, as by comminution, dispersion arid or solvation, without separation of such product from the anode.
