Metasilicic acid obtained from aqueous solution of sodium silicate was allowed to react with excess glycidol. The obtained semi-product was hydroxyalkylated with ethylene carbonate to obtain oligoetherol. The structure of the oligoetherol was determined by chemical and instrumental methods. Further the oligoetherol was used to obtain foamed polyurethane compositions. The properties of the foams were also studied.
