Synthesis and research of aromatic polyiminoesters

The synthesis of aromatic polyiminoesters by polycondensation of bis-imidoyl chlorides with diamines was performed. Optimal conditions for polycondensation processes with various nucleophiles were determined. The reaction of non-equilibrium polycondensation of imidoyl chlorides of mono-and dicarboxylic acids with bisphenols produced new polymers, the structure of which was established by elemental analysis and IR spectroscopy. It is shown that polymers have high temperature resistance. Press materials based on them, which are characterized by high deformation and strength indicators comparable to materials based on aromatic polyamides and polybenzimidazoles, were studied.
