Abstract

The present invention provides a polymer compound which comprises both repeating unit “a” represented by the following general formula (1-1) and repeating unit “b” represented by the following general formula (1-2), and has a weight average molecular weight in the range of 1,000 to 500,000,

wherein R 1 represents a hydrogen atom or a methyl group, R 2 represents a single bond, an ester group, or a linear, branched, or cyclic hydrocarbon group having 1 to 12 carbon atoms which may have either or both of an ether group and an ester group, Z represents a phenylene group, a naphthylene group, or an ester group, and “a” and “b” satisfy 0<a<1.0 and 0<b<1.0. There can be provided a polymer compound having a specific super strongly acidic sulfo group, which is soluble in an organic solvent, and suitably used for a fuel cell or a dopant for a conductive material.
