Abstract

A polymer-modified polyol is formed by polymerising an olamine, particularly an alkanolamine, with an organic polyisocyanate in the presence of a polyol. The alkanolamine reacts polyfunctionally with the polyisocyanate to produce polyaddition products. The polyaddition products may constitute a stable dispersion in the polyol and the resulting polymermodified polyol is particularly useful as a polyol starting material for reaction with a polyisocyanate in the manufacture of polyurethane foam.
