ABSTRACT:
A process is disclosed for producing resilient polyurethane foams by foaming an organic polyisocyanate, an iso-cyanate-reactive compound and a fusible polymer. The improvement in the hardness of the foams is achieved without adversely affecting the other properties of the foams, such as tensile strength and elongation.
