N D Zelinskii Institute of Organic Chemistry, Russian Academy of Sciences, 47 Leninskii Prosp., Moscow, 117913, Russia The interaction of the demethylation product of 1, 3, 5-trinitrobenzene2, 4, 6-trinitrotoluenewith fluorinated alcohols followed by reduction of the perfluoroalkoxy-substituted m-dinitrobenzenes thus formed led to the formation of new fluorinated diamines. The reaction of these diamines with aromatic tetracarboxylic acid dianhydrides led to the formation of new fluorinated polyimides combining solubility in organic solvents with large windows between glass transition and degradation temperatures.
