ABSTRACT:
Polypyrroles are prepared by electrochemical polymerization, in particular anodic oxidation, of pyrrole alone or together with comonomers, in an aqueous electrolyte solvent which consists of not less than 50% by weight of water, in the presence of aromatic sulfonic acids and/or their salts as conductive salts. The process gives polypyrrole films which have good mechanical properties and high electrical conductivities.
