A new polyarylenevinylene containing vinyl pyrrole (PVP) was obtained from the monomer, 2,5-bis (methylenedimethylsulfonium) chloride pyrrole, which was prepared from 2,5-dimethylpyrrole by the modified sulfonium polyelectrolyte precursor route. The polymerization conditions for the preparation of precursor polymers are described. The highest yield was obtained when the PVP was synthesized at -40 degrees C with the monomer/base concentration ratios of 0.5/0.2 and thermally eliminated at 220 degrees C. The electrical conductivity of the PVP synthesized with aforementioned conditions was given as 6.8 x 10(-7) Scm(-1).
