Abstract
Carboxyalkyl cellulose polymer network having superabsorbent properties.
Claims20
A water-swellable, water-insoluble crosslinked carboxyalkyl cellulose, wherein the carboxyalkyl cellulose is obtained from a pulp having a kappa value of from about 1 to about 65.
A composition, obtainable from reacting a carboxyalkyl cellulose obtained from pulp having a kappa value of from about 1 to about 65 with a crosslinking agent in an amount effective to render the carboxyalkyl cellulose insoluble in water.
A composition obtainable from a method comprising:
- (a) treating a carboxyalkyl cellulose obtained from pulp having a kappa value of from about 1 to about 65 with a crosslinking agent in an amount effective to render the carboxyalkyl cellulose insoluble in water to provide a reaction mixture;
- and
- (b) crosslinking the reaction mixture to provide the composition.
