ABSTRACT:
Disclosed is a method for producing a water-swellable, generally water-insoluble modified polysaccharide having improved age-stable absorption properties. The method involves forming a mixture of a modified polysaccharide, water, and, optionally, a crosslinking agent, recovering the modified polysaccharide from the mixture and, optionally, heat-treating said recovered modified polysaccharide.
