    • 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.
    • 公开了新型多糖吸收剂和提供具有优选的年龄稳定吸收性能的水溶胀性水不溶性改性多糖的方法。 新型多糖吸收剂和方法提供天然吸收剂和优选的吸收老化特性。 将天然的水溶性羧基烷基多糖溶解在水中并回收并进行热处理以形成水溶胀和水不溶性的羧基烷基多糖。 在负载值下具有优选初始吸收性的水溶胀性和水不溶性羧基烷基多糖在至少约60%相对湿度下老化。 在一个方面,水溶性羧烷基多糖的水性混合物具有约4.0至约7.5的pH。 具有优选的载荷吸收性和优选的老化特性的天然材料产品在老化后保持初始载荷分析测试值的至少约50%。
