Benzophenone-type unsymmetrical substituted aromatic diamines of general formula 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. Key Words: Polyimides (PIs), organosoluble, aromatic diamines, aromatic tetracarboxylic acids dianhydrides, high temperature solution polycyclocondensation
