Abstract
The present invention provides a polymer compound for a conductive polymer, having one or more kinds of repeating units 'a' represented by the following general formula (1), the polymer compound for a conductive polymer being synthesized by ion exchange of a lithium salt, a sodium salt, a potassium salt, a sulfonium compound salt, or a nitrogen compound salt of sulfonic acid residue with a weight average molecular weight in the range of 1,000 to 500,000, wherein Rrepresents a hydrogen atom or a methyl group, Rrepresents a fluorine atom or a trifluoromethyl group, 'm' represents an integer of 1 to 4, and 'a' satisfies 0<a≤1.0. There can be provided a polymer compound for a conductive polymer having a specific superacidic sulfo group that is soluble in an organic solvent and suitably used for fuel cells or a dopant for conductive materials.
