Abstract
New poly[(4-fluorophenyl)quinoxaline]s were prepared by polycyclocondensation of bis(ophenylenediamines) with bis(á-diketone)s – bis(4-fluorophenylglyoxalyl)arylenes. The effect of fluorine atoms in poly(phenylquinoxaline)s on the solubility, thermal characteristics and other properties of the resulting polymers was studied. As the quinoxaline rings act as the activators of fluorine atoms in the reactions of aromatic nucleophilic substitution, poly[(4-fluorophenyl)quinoxaline]s were transformed into poly(phenylquinoxalines) containing aroxy, p-carboxyphenoxy and aroxysulfonic acids groups.
