A new class of nonionic superabsorbant hydrogels based on the graft copolymerization of cellulose derivatives or poly(vinyl alcohol) with poly (ether urethane-urea) polymers has been developed. This new class of hydrogels exhibit a wide array of swelling behaviors under conditions of physiological and commercial importance. Graft copolymers prepared from TPHU and HPMC display very large swelling under a variety of conditions, both in terms of % weight and % volume increase.
