Abstract
A novel method for the preparation of water-soluble polypyrrole graft copolymers with polyamines or polyimines is described. The polyreactio n is performed in acidic solution by using chemical oxidants, e. g. ir on(III) chloride or ammonium peroxodisulfate. The graft copolymers sho wed electrical semiconductivity in the undoped state which can be plac ed between the high conductivity of polypyrrole and the nonconductivit y of the polyimine. Their thermal stability at 250 degrees C is improv ed compared to polypyrrole. The novel graft copolymers are soluble in water over a wide pH range and have a good processability.
