| titleOfInvention | Polysaccharide absorbent and method |
| abstract | Disclosed are novel polysaccharide absorbents and method for providing a water-swellable, water-insoluble modified polysaccharide having preferred age-stable absorption properties. The novel polysaccharide absorbents and method provide a natural-based absorbent and preferred aging characteristics for absorbency. A natural-based water-soluble carboxyalkylpolysaccharide is dissolved in water and recovered and heat-treated to form a carboxyalkyl polysaccharide which is water swellable and water insoluble. The water-swellable and water-insoluble carboxyalkyl polysaccharide having a preferred initial absorbency under load value is aged under at least about 60 percent relative humidity. In one aspect the aqueous mixture of water-soluble carboxyalkyl polysaccharide has a pH between about 4.0 and about 7.5. The natural-based material product having preferred absorbency under load and preferred aging characteristics retains at least about 50 percent of an initial Absorbency Under Load analytical testing value after aging. |
