Abstract
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 2 SO 4 , R'SO 2 Cl or R" 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 2 SO 4 , the R'SO 2 groups of R'SO 2 Cl, or the R" 3 Si groups of R" 3 SiCl are covalently linked to the nitrogen atoms of the polymer.
