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 an R + donor compound, where R is an organic group, e.g., methyl iodide, and forming an electrically conductive polymer in which the R groups are covalently linked to the nitrogen atoms of the polymer.
