ABSTRACT OF THE DISCLOSURE The modification of polyether polyols by their reaction with epoxy resin and alkylene oxides is described. The modified polyols of 2000 to 7000 molecular weight produce flexible polyurethane foams that have higher load bearing properties than foams made with nonmodifed polyols. The ability of a modified polyol to make a higher load bearing foam is related to the position in the polyol chain the epoxy resin is added.
