THE AROMATIC AND HETEROCYCLIC DINITRILES AND THEIR POLYMERS. Ⅸ. THE POLYMERIZATION KINETICS OF 4, 4'-BIPHENYLDICARBONITRILE*

Received Date: 16 May 1984

The polymerization kinetics of 4,4'-biphenyldicarbonitrile catalyzed by complex of 4,4'-biphenyl-dicarbonitrile with ZnCl2 was studied. The cyano group concentration was measured by infrared spectroscopic analysis using potassium ferricyanide as the internal reference. The results proved that the polymerization is a second order reaction, and the activation energy of polymerization is 12.4 kcal/mol. The polymerization rates of 4,4'-biphenyldicarbonitrile catalyzed by other seven complexes were also measured.The polymerization mechanism was discussed.
