ABSTRACT:
Production of electrically conductive polypyrrole powder, by treating a liquid pyrrole with a solution of a strong oxidant, capable of oxidizing pyrrole to a pyrrole polymer, and oxidizing the pyrrole by such strong oxidant in the presence of a substantially non-nucleophilic anion and precipitating a conductive polypyrrole powder. The strong oxidant, e.g., Fe.sup.3+ ion, and non-nucleophilic anion, e.g., sulfate or chloride ion, can be derived from a single compound, e.g., FeCl.sub.3 or Fe.sub.2 (SO.sub.4).sub.3. The anion serves as dopant for the polypyrrole. The reaction can be carried out in aqueous solution or in an organic solvent medium, such as acetonitrile.
