Abstract
Isocyanate-terminated-prepolymers prepared from polyoxyalkylene polyether polyols having low unsaturation are suitable for producing polyurethane molded foam having exceptional physical properties. Preferably, the foams are all water blown, and process well. The foams are noted for concomitant increases in both tensile strength and elongation as well as displaying excellent wet set and other properties.
