ABSTRACT OF THE DISCLOSURE The modification of rigid amino polyols by their reaction with epoxy resin and alkylene oxides is described. The modified polyols produce rigid polyurethane foams that have higher heat distortion temperatures and better low temperature properties than foams made with nonmodified polyols. The viscosities of the epoxy resin-modified amino polyols are not signifi- cantly different than those of the prior ar? amino polyols although they are of a higher functionality.
