Abstract

A soluble aniline conducting polymer characterized in that said conductive polymer comprises as a repeating unit an alkoxyl group-substituted aminobenzenesulfonic acid, its alkali metal salts, ammonium salts and/or substituted ammonium salts, and is a solid having a weight average molecular weight of about 1900 or more at room temperature, a conductive composition and electric conductor comprising the same, and a method for producing a soluble aniline conducting polymer having a weight average molecular weight of 10,000 t 3,240,000 characterized by polymerizing at least one compound (1) selected from the group consisting of an acidic group-substituted aniline, its alkali metal salts, ammonium salts and substituted ammonium salts in a solution containing a basic compound (2) using an oxidizing agent.
