Abstract
Abstract Processable conductive polymers and a method for their production are disclosed. The processable conductive organic polymers comprise the cationic electropolymerized polymer of an electropolymerizable monomer and, as a counterion in affiliation therewith, a polymer having anionic surface character, the counterion polymer being effective to confer processability. During the production of the conductive polymer from the electropolymerizable monomer, a polymeric electrolyte having anionic surface character is present as a dispersed phase and functions as the counterion.
