Abstract

Abstract A polymer solution comprising a polymer comprising at least 50 mole % of recurring units represented by the following formula (1): ##STR1## wherein R 1 through R 4 , which may be the same or different, represent a hydrogen atom or an alkyl or alkoxy group having 1 to 5 carbon atoms, with the proviso that the case where all of R 1 through R 4 represent a hydrogen atom is excluded, a dopant and an organic solvent has a high electric conductivity and is valuable as an electrolyte of a battery, an electrolyte of a capacitor, and the like. A shaped article obtained by shaping this solution and removing the organic solvent from the shaped article has a high electric conductivity and is valuable as various electronic parts.
