Abstract : In the patent thermally stable quinoxaline polymers are prepared by solution polycondensation of certain aromatic heterocyclic fused tetraamines with aromatic dibenzils. The high thermal stability, the high glass transition temperature, or the lack of such a temperature, and the solubility of the polymers in aprotic solvents render them especially useful as adhesives and in high temperature applications such as in the fabrication of plastic composites and protective coatings.
