Abstract
A conductive polymer composition comprises a conjugated double bond-bearing polymer and a composite dopant consisting essentially of an organic anion derived from an anionic surface active agent and an inorganic anion derived from a transition metal salt. A process for preparing the conductive polymer composition is also described wherein the polymerizable proceeds rapidly in coexistence of the organic anion and the inorganic anion. Addition of fine particle of an oxide is effective in film formation on substrates.
