Polyetherols and polyurethane foams from starch

New method of synthesis of polyetherols from starch in aqueous solution was elaborated. Starch was converted into polyetherols by reactions with alkylene carbonates. The products are mixtures of starch-derived polyetherols and products of hydroxyalkylation of water. The elaborated method can be usef...
