Abstract
A high-strength polymer-modified polyol comprises a polyol and from 40 to 80% by weight of the reaction product of a polyisocyanate and a tertiary-N-polyolamine based on the combined weight of the polyol and reaction product. Also included are methods of forming the polymer-modified polyol; a polymer-modified polyol obtained by dilution of the high strength polymer-modified polyol; the use of the polymer-modified polyols in the manufacture of polyurethane products and the polyurethane products so obtained. The polymer-modified polyols are particularly useful for preparing highly resilient flexible foams.
