New tetraamine monomer bis(2,3‐diaminophenoxy)benzene (BDAPB) was synthesized by reducing corresponding precursor bis(2,3‐dinitrophenoxy)benzene with hydrazine hydrate. Hyperbranched polyimide with terminal amino groups was synthesized by means of the one‐stage high temperature polycondensation of BDAPB with 2,2‐propylidene‐(1,4‐phenyleneoxy)diphthalic acid in catalytically active solvent – molten benzoic acid at 140°C by the scheme A2+B4. Examples of polymer‐analog transformations were shown of terminal amino groups to form acetamide and phthalimide derivatives.
