Abstract of the Disclosure Highly branched polyether polyols of high molecular weight (such as over 12,000) are made by coupling an alkoxylated polyglycerol, by reaction of the sodium alcoholate of the oxyalkylated polyglycerol with a diben- zenesulfo or dieoluenesulfo ester of a diol containing 2 to 6 carbon atoms. Products obtained are viscous resinous products which are particularly suitable for use as hydro- philic water-swellable gels and other purposes.
