Pyrrole monomer substituted in the 3- and 4-positions by cyano and methyl groups (3-Cyano-4-methylpyrrole) was synthesized and it was polymerized by chemical oxidation method, using FeCl3 as oxidizing agents. The obtained polymer was soluble in general organic solvent, but had very low conductivity. We also report a method of preparing conducting copolymers of 3-Cyano-4-Methylpyrrole and pyrrole.
