Preparation of polyfunctional oligoethers

Abstract

Copolymerization of epichlorohydrin with allyl glycidyl ether under the action of boron trifluoride tetrahydrofuranate in diethyl ether and dimethoxyethane was studied under the conditions of synthesis of alkyl ether and diols where water was used to produce terminal hydroxy groups. ¹H NMR spectroscopy showed the formation of a copolymer. The integrated intensity ratio for the signals related to allyl and other groups showed that the rate of allyl glycidyl ether introduction into the copolymer is higher than that of epichlorohydrin. Alkyl- and hydroxy-containing oligoethers with enhanced content of functional groups of different nature were obtained by polymer analogous reaction.
