Preparation of polymers by polycyclization reactions Communication 2. Formation of polybenzimidazoles

  • Published:
Bulletin of the Academy of Sciences of the USSR, Division of chemical science Aims and scope

Summary

  1. 1.

    The effect of various factors (reaction temperature and time, relative amounts of the reactants, and various monofunctional additions) on the formation of a polybenzimidazole from 3,3′,4,4′-biphenyltetramine and diphenyl sebacate was investigated.

  2. 2.

    A mechanism is proposed for the formation of polybenzimidazole which consists of two stages: a) formation of a poly (amino-amide), and b) closing of benzimidazole rings.
