The new method of synthesis of N-phenilsubstitution polydiacylamines

The opportunity of transformation of polycarboxyimidates, obtained by polycondensation dicarboxylic acides with imidoylchlorides of dicarboxylic acides in aromatic N-phenilsubstitution polydiacylamines is found out. Such regrouping occurs as the result of thermal influence at 150 °C during 10 h, and in the solution of N-methylpyrrolidinone at the expiration of 6-8 hrs at 120 °C. The obtained polymers soluble in organic solvents and also posses high stability to thermooxidization destruction.
