Poly(4-fluorophenylquinoxaline)s were prepared by polycyclocondensatio
n of new ketone)s-bis(4-fluorophenylglyoxalyl)arylenes-with bis(o-phen
ylenediamine)s. The effect of fluorine atoms in poly(phenylquinoxaline
)s on the solubility and thermal characteristics of the resulting poly
mers was studied. The possibility of using poly(4-fluorophenylquinoxal
ine)s in the synthesis of polymers with substituents varying in bulkin
ess and structure is discussed.
