Polymers from nitriles. VII. Polymerization of fumaronitrile with triethylamine as initiator

The reaction of fumaronitrile with triethylamine in bulk at 295–353 K gives in high yields dark‐colored polymers. The polymerization occurs at one of the two nitrile groups and not at the (CC) double bond. The kinetics of the reaction were investigated and the polymers characterized analytically.
