ABSTRACT:
The invention disclosed is for new improved hydrophilic crosslinked polyurethane foams prepared by reacting a blend of a monomeric polyol and polyoxyalkylene glycol (the --OH groups of said blend being capped with a polyisocyanate) with large amounts of an aqueous reactant. The resultant foams may be characterized with a broad spectrum of improved properties including hydrolytic stability and tensile strength.
