FIELD: polymer production.
SUBSTANCE: invention relates to polyamides that can be used in a variety of arias as high-strength and high-temperature-resistant coatings, plastic binders, glass plastics, and films. Two-stage production process comprises preparation of polyimidates via non-equilibrium polycondensation of bis-phenols with N-phenylimine chloride based on mono- and dicarboxylic acids, after which resulting polyimidates are subjected to Chapman rearrangement at 240-260оС for 5-6 h.
EFFECT: enabled production of polymers showing good solubility and elevated treatment resistance.
