Benzophenone-type unsymmetrical substituted aromatic diamines of general formula [GRAPHICS] were prepared starting with p-nitrobenzoyl chloride and substituted benzenes. Interaction of the diamines obtained with aromatic tetracarboxylic acids dianhydrides under the conditions of high-temperature solution polycyclocondensation in m-cresol led to the formation of new high molecular weight organosoluble polyimides.
