Abstract
This invention relates to novel polyether polyols and to a process for their production. These polyether polyols are prepared by forming a polyhydroxyl group containing component in a first step by the reaction of a triazole-group containing compound with a compound that contains at least one functional group that is capable of reacting with the amine groups of the triazole group containing compound, and reacting the hydroxyl-group containing component with an alkylene oxide to form the polyether polyol of the invention. The present invention also relates to isocyanate-reactive compositions comprising these novel polyether polyols, and to a process for the production of a polyurethane comprising reacting a polyisocyanate with the novel polyether polyols of the present invention.
