SYNTHESIS AND INVESTIGATION OF NEW POLY(A RYLQUINOXALINE)S

New 4,4'-bis(arylglyoxaloyl)benzophenones were prepared on the basis o f 4,4'-diiodobenzophenone-a derivative of chloral. The reaction betwee n 4,4'-bis(arylglyoxaloyl)benzophenones and aromatic bis(o-phenylenedi amine)s leads to poly(arylquinoxaline)s containing phenyl, diphenyl, d iphenyl ether, diphenyl thioether, and benzophenone side groups. The r esulting polymers combine enhanced solubility and high thermal charact eristics. The films were prepared and their mechanical and dielectric properties were studied.
