Influence of the chemical structure of diphenols on the course of high-temperature nonequilibrium polycondensation reactions in the synthesis of polyarylates

Аннотация

Potentiometric titration and PMR spectroscopy in non-aqueous media determined quantitative physicochemical parameters reflecting the reactivity of diphenols and their conjugated diphenoxide anions. A large series of correlation relationships was obtained between the above parameters and data of kinetic studies of reactions of nonequilibrium high-temperature polyesterification in the synthesis of polyarylates and aromatic polyethers. The results of experimental and theoretical studies were the establishment of the mechanisms of these reactions.
