Abstract
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 a multiprotic acid in the form of an aromatic multisulfonic acid, such as m-benzene disulfonic acid, and forming an electrically conductive polymer having high thermal stability at elevated temperature, e.g., 180.degree. C. in air.
