New polyphenylquinoxalines (PPQ's) prepared from reaction of novel bis(alpha-diketones) with aromatic bis(o-diamines). Contain alkylenedioxy groups in repeating units. Lower glass-transition temperatures and melt viscosities and better processability than all-aromatic PPQ's. Tensile strength, modulus, elongation, adhesive strength, fracture energy, and solvent resistance of new polymers comparable with properties of known PPQ's. Useful as adhesives, coatings, films, and molded products, particularly for aerospace applications.
