ABSTRACT:
Disclosed is a water-swellable, water-insoluble sulfonated cellulose having improved absorption properties. One embodiment of the present invention concerns a water-swellable, water-insoluble sulfonated cellulose having an average degree of sulfonic group substitution from about 0.2 to about 0.5 that exhibits an initial Absorbency Under Load value of at least about 8 grams per gram. The sulfonated cellulose may be used in disposable absorbent products.
