The present paper describes some recent results concerning processable electroconducting materials prepared starting with properly substituted pyrrole derivatives. The first approach was based on the preparation of a precursor polymer by free radical polymerization of N-vinylpyrrole. This insulating, soluble and filmable polymer could be converted into an electroconducting product by intramolecular ladderization through oxidation of the pyrrole side chains. In the same frame the chemical homo and copolymerization of 3-decylpyrrole with pyrrole allowed to produce soluble or swellable polymers having conductivity variable with copolymer composition. The ladder formation and internal plastification by the long aliphatic side chain have been combined to give polymers derived from 3-decyl-N-vinylpyrrole and its copolymers with N-vinylpyrrole. Relationships between electroconductivity and controlled structure of the subject materials are discussed with reference to their blends with insulating plastomers.
