ABSTRACT:
Disclosed is a method for producing a water-swellable, generally water-insoluble, carboxyalkyl polysaccharide having improved absorption properties. The method involves forming a solution of carboxyalkyl polysaccharide and water, recovering the carboxyalkyl polysaccharide from the solution and heat-treating said recovered carboxyalkyl polysaccharide. Also, described is a carboxyalkyl polysaccharide having improved absorption properties.
