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 cation donor compound, such as R.sub.2 SO.sub.4, R'SO.sub.2 Cl or R'.sub.3 SiCl, where R, R' and R' are alkyl or aryl, such as dimethyl sulfate or tosyl chloride, and forming an electrically conductive polymer in which the R groups of R.sub.2 SO.sub.4, the R'SO.sub.2 groups of R'SO.sub.2 Cl, or the R'.sub.3 Si groups of R'.sub.3 SiCl are covalently linked to the nitrogen atoms of the polymer.
