A possibility for the transformation of polyphenyl imidates, obtained by polycondensation of bisphenols with imidoyl chlorides of mono- and dicarboxylic acids, into N-phenyl-substituted aromatic polyamides and poly(N-benzoylamines) has been discovered. Such a rearrangement resulted from heating at 260–340 °C for 13–17 h, whereas in diphenyl ether solution at 240 °C for 10–14 h. The polymers synthesized are soluble in organic solvents and possess high stability against thermooxidative destruction.
