New Catalytic Polymerization of Pyrrole

Abstract Pyrrole can be easily polymerized to produce polypyrrole by using an AlCl3–CuCl–O2 cayalytic system. The yield of polypyrrole was very high and more than 600% based on the amount of CuCl used. The conductivity of the pressed polypyrrole was 10−2 S cm−1.
