Substantially amorphous, high molecular weight polyaniline which is processable into shaped articles such as fibers is disclosed. Polyaniline base made by standard procedures is subjected to extraction to remove impurities and lower molecular weight fractions. The resulting high molecular weight base, which is partially crystalline and insoluble in NMP and concentrated H.sub.2 SO.sub.4, is converted to an amorphous material soluble in NMP and concentrated H.sub.2 SO.sub.4, by a two step process involving conversion to a salt, and reconversion to a base. Fibers prepared from the high molecular weight material exhibit conductivities in the range of about 50 to 100 S/cm.
