PURPOSE: To obtain the subject polymeric film, containing a polymer comprising acid group-substituted anilines as a recurring unit in a specific aniline-based polymeric film in a dedoped state undergoing the deacidifying or reducing treatment, good in electric conductivity and heat and weather resistances and useful for electrode materials, etc.
CONSTITUTION: This electrically conductive polymeric film is obtained by forming an aniline-based polymeric film (m) in a dedoped state, undergoing the deacidifying or reducing treatment and represented by formula I [R1 to R18 are each H, a 1-4C alkyl, a l-4C alkoxy, hydroxyl group, nitro, amino or a halogen; (x) is an optional number of ≤1; (n) is the polymerization degree and is 2-5000] and then adding soluble aniline-based electrically conductive polymers which are in the form of a solid at normal temperatures, having ≥70% acid group-substituted aniline comprising the acidic group represented by formula II [A is sulfone, carboxyl, its alkali metallic salt or a (substituted)ammonium salt; B is H, an alkyl, an alkoxy, etc.), etc., or its salts as a recurring unit and ≥1900 weight-average molecular weight as a dopand together with a solvent to the film, carrying out the doping treatment, then allowing the film to stand or heat-treating the film.
