Highly Absorbent Polymeric Compositions from Polyhydroxy Polymer Graft Copolymers Abstract of the Disclosure Absorbent compositions comprising graft copolymers of acrylonitrile and starch, or related polyhydroxy polymers, are prepared by improved methods of synthesis. Mixing the acrylonitrile with selected water-soluble acrylic comonomers enables unexpected improvements including reduction of the saponification time, and preparation of products which absorb over 5000 times their weight of deionized water.
