Oxidizing Effect on Chemical Polymerization of Pyrrole Monomer in Anhydrous Media

Abstract

The chemical polymerization of pyrrole monomer with ferric chloride (FeCl₃), copper(II) perchlorate [Cu(ClO₄)₂], ammonium peroxodisulfate [(NH₄)₂S₂O₈] and periodic acid (H₅IO₆) in anhydrous medium was investigated by using conductivity measurements, thermal analysis methods (TG, DTA), UV-vis and FTIR spectroscopies. The results indicated that the best oxidation reagent for chemical polymerization of pyrrole in anhydrous medium was Cu(ClO₄)₂. It was also determined that FeCl₃, which is both a Lewis acid and oxidant for chemical polymerization, adds to polymer chain such as proton.
