摘要

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.
