Abstract

Polyethers are prepared by reacting polyhydroxy compounds with alkylene oxides alone or together with polyepoxides, using dimethyl sulphoxide as reaction medium. The polyhydroxy compounds must melt at temperatures above 120 DEG C. or melt only with decomposition and must be soluble in dimethyl sulphoxide. Suitable compounds are trimethylolethane, pentaerythritol, tetramethylolcyclohexanol, sucrose, a -methyl glucoside and other sugars, mannitol, inositol and quebrachitol. Specified alkylene oxides are ethylene, propylene and butylene oxides. Specified polyepoxides are 1:2-3:4-diepoxybutane, diallyl ether dioxide and 2,6-dioxaspiro-[3,3]-heptane. The reaction may be effected at temperatures of 50 DEG to 150 DEG C. and in the presence of alkaline catalyst. Examples are given in which the reactions are carried out under nitrogen, the catalyst neutralised with adipic acid and then the polyethers bleached with hydrogen peroxide. According to the Provisional Specification, epihalo hydrins such as epichlorhydrin, may be used in place of or in admixture with the alkylene oxides.
