Aromatic poly(phenylquinoxaline-esters) have been synthesized by solution polycondensation of bis(hydroxyphenylquinoxaline)s with two diacid chlorides containing preformed ester units. Also, poly(phenylquinoxaline-esters) containing pendent imide rings have been synthesized by the same procedure using bis(hydroxyphenylquinoxalines) and two diacid chlorides containing preformed imide rings. All these polymers were characterized by infrared spectra, elemental analysis, viscometric measurements and thermogravimetric data.

New aromatic polyesters have been synthesized by solution polycondensation of dihydroxyphenylquinoxalines with diacid chlorides containing preformed imide cycles. The thermal stability of these compounds is discussed and compared with related phenylquinox
