Abstract : Thermally stable benzimidazonaphthyridine polymers are synthesized by the polycondensation of an aromatic tetraamine and 4,4',5,5'-tetracarboxy-8,8'-biquinoline dianhydride. The polymers are useful in high temperature applications such as in the fabrication of plastics, composites, fibrous materials, protective coatings and films.
