Notes:
Homopolymers and copolymers of fumaronitrile, maleonitrile, and succinonitrile have been prepared by using medium high temperature free-radical initiators. Black, nonfusible but soluble polymers were obtained. The spectroscopic and chemical evidence indicated a structure containing α-pyrrolenine rings and no free nitrile groups in the fumaronitrile and maleonitrile polymers and 1-pyrroline rings and free nitrile groups in the succinonitrile polymers. The polymers possessed good thermal stability, free spin concentration of 1017-1018 spins/g, and an ac conductivity at room temperature in nitrogen of 10-6 to 10-8 ohm-1 cm-1.
