Investigation of the elementary reactions in the synthesis of poly(hydroxethers) in dipolar,aprotic solvents

The effect of the hydroxyl groups of various phenols on the course of the reaction of their alkali metal salts with epichlorohydrin in dipolar, aprotic solvents has been studied. It was found that the presence of phenols in the system leads to the formation of a complex salt of the type (ArO … H … OAr)^?Mt⁺, and to a considerable decrease in the reaction rate. The mechanism of the reaction of chlorohydrin ethers of phenols with alkali metal phenolates was also studied. The effect of various factors on the course of the reaction of glycidyl ethers with phenols was determined by kinetic measurements.
