Electroinitiated Polymerization through Acetylene and Nitrile Group Bonds.
Abstract
The polymerization of monomers through acetylenic and nitrile groups has been studied. In the cathodic polymerization of phenylacetylene in dimethylformamide, an anionic polymerization mechanism is indicated. The polymer of molecular weight approx. 3000 has been fractionated and the fractions characterized by ir, uv, and nmr spectroscopy. Evidence is presented for a conjugated polyene structure formed from cis and trans structural units combined in a predominantly head-to-tail fashion. Similarly, the polymerization of benzonitrile in dimethylformamide at the cathode leads to a polymer with conjugated -C=N- bonds. Mass spectroscopy did not reveal the presence of any cyclic trimer of benzonitrile. Infrared absorption bands at 1/1605 cm and 1/1520 cm established the formation of -C=N- conjugation in polybenzonitrile.
