Abstract
A process for the preparation of an organic solvent soluble ion-doped poly(alkyl-substituted pyrrole) which comprises dissolving an alkyl-substituted pyrrole compound represented by formula (I) in an organic solvent, oxidation-polymerizing the dissolved alkyl-substituted pyrrole in the presence of at least one oxidation polymerization agent selected from the group consisting of a ferric salt and a copper (II) salt to form an ion-doped poly(alkyl-substituted pyrrole), next adding water to the polymerization reaction system thus obtained and then recovering an organic solvent soluble ion-doped poly(alkyl-substituted pyrrole): ##STR1## wherein X represents an alkyl group; and Y represents a hydrogen atom or an alkyl group.
