Abstract

An oriented electrically conductive polypyrrole article having a degree of orientation of at least 40% in at least one direction; an electrically conductive polypyrrole article having an electrical conductivity of at least 100 S/cm.; a process for producing an electrically conductive polypyrrole having improved electrical conductivity and stretchability, which comprises electrolytically polymerizing pyrrole and/or a pyrrole derivative in an electrolytic solution comprising an electrolyte and a solvent, said polymerization being carried out at a temperature of 0.degree. to -50.degree. C.; and a process for producing an electrically conductive polypyrrole article having improved electrical conductivity, which comprises stretching an electrically conductive polypyrrole article in at least one direction.
