Thermal polycyclocondensation of bis-aminophenylquinoxalines with the dianhydride of 1,4,5,8-naphthalene tetracarboxylic acid☆

Abstract The thermal polycyclocondensation of bis-aminophenylquinoxalines with the dianhydride of 1,4,5,8-naphthalene tetracarboxylic acid has been studied. The optimal regimes of conducting the process have been substantiated. The possibility of obtaining moulded material based on the polynaphthylimidophenylquinoxalines by the reaction moulding method has been demonstrated.
