Production of base-type conductive polymers, particularly from the family of conductive polyaniline, by reacting a base-type non-conductive polymer containing carbon-nitrogen linkages, e.g., polyaniline, with an anhydride, such as R--SO 2 --O--SO 2 --R', R--CO--O--CO--R', or R--CO--O--SO 2 R', or mixtures thereof, where R and R' are alkyl or aryl, e.g., tosylic anhydride or benzophenone tetracarboxylic dianhydride, and forming an electrically conductive polymer in which the SO 2 R and COR groups are covalently linked to the nitrogen atoms of the conductive polymer and the anion of the conductive polymer is the SO 3 R' or O 2 CR' group. |
