Abstract
Abstract Polyether polyols are modified by reaction with alkylene oxides and amino alcohol-epoxy resin adducts. The adducts are the reaction product of an epoxy resin and amino alcohol of the formula: ##STR1## wherein: x ranges from 1 to 4, y ranges from 1 to 40, and R is an alkyl of from 1 to 4 carbon atoms. These polyether polyols are used to prepare flexible polyurethane foams.
