Abstract
Method for making a sulfoalkylated cellulose polymer network having superabsorbent properties.
Claims20
A method for making a composition, comprising reacting a sulfoalkyl cellulose and a synthetic water-soluble polymer with a crosslinking agent, wherein the crosslinking agent reacts with at least one of the sulfoalkyl cellulose or synthetic water-soluble polymer.
A method for making a composition, comprising
- (a) combining a sulfoalkyl cellulose, a synthetic water-soluble polymer, and a crosslinking agent in an aqueous solution to provide a reaction mixture;
- (b) precipitating the reaction mixture by addition of a water-miscible solvent to provide a precipitated mixture;
- (c) collecting the precipitated mixture;
- and
- (d) crosslinking the precipitated mixture to provide the composition.
