Abstract

The oligomer of fumaronitrile 3, obtained by anionic polymerisation of fumaronitrile with butyllithium, is able to isomerise fumaronitrile to maleonitril. Kinetics and thermodynamics are examined and a model for the mechanism is proposed.

Fumaronitrile can polymerize quantitatively under mild conditions with anionic initiators. With the initiator butyllithium the kinetics is examined with the help of the 'H NMR method. The mechanism of the polymerisation is described which is different in polar and unpolar solvents. In THF an electro

## Abstract Bernsteinsäuredinitril wurde in Gegenwart von anionisch angreifenden Katalysatoren zu Polymeren umgesetzt. Die Polymerisation des Nitrils z. B. mit Natriummethylat in Methanol führt zum Poly(1‐pyrrolin‐2‐yl‐5‐ylidennitrilo), welches Halbleitereigenschaften mit σ~300°K~ ∼ 10^−8^Ω^−1^cm^−
