SUPERABSORPTIVE MATERIAL AND METHOD OF MAKING SAME

A superabsorbent polysaccharide derivative is obtained by oxidation of the polysaccharide to the extent that the derivative contains 0.2-0.3 carboxyl group per monosaccharide unit and cross-linking the oxidized polysaccharide with 0.0001-0.2 equivalent of cross-linking agent per monosaccharide unit....

Zusammenfassung:	A superabsorbent polysaccharide derivative is obtained by oxidation of the polysaccharide to the extent that the derivative contains 0.2-0.3 carboxyl group per monosaccharide unit and cross-linking the oxidized polysaccharide with 0.0001-0.2 equivalent of cross-linking agent per monosaccharide unit. The polysaccharide may also be cross-linked prior to oxidation.
