ABSTRACT:
Absorbent polymeric compositions are prepared by drying aqueous dispersions of physical mixtures of polyhydroxy polymers, such as starch, with carboxylate-containing synthetic polymers, such as saponified polyacrylonitrile of partially saponified polyacrylamide, and then curing the resulting dry solids with either heat or prolonged standing at room temperature. These compositions typically absorb several hundred times their weight of deionized water.
