A method of synthesis of new fluorine-containing tetraamine, 2,2-bis[4-(3,4-diaminophenoxy) phenyl]hexafluoropropane, has been developed; the tetraamine has been used as the initial compound for preparing poly(phenylquinoxaline)s in both supercritical carbon dioxide and solution. Thermal characteristics of fluorine-containing poly(phenylquinoxaline)s have been studied. There is a bimodal particle size distribution at the used polymer concentration (C (pol) = 0.1 wt %) according to dynamic laser light scattering data.
