Abstract : Thermally stable aryloxybenzimidazo benzophenanthroline polymer compositions are synthesized by the condensation of a tetraamino bisaryloxy compund with an aromatic tetracarboxylic acid or dianhydride thereof. The high thermal stability of the polymers and their solubility in a variety of organic solvents render them especially suitable for use in high temperature applications such as in fabrication of plastic composites and protective coatings.
