Classification: A61L,C08B

Abstract:
Superabsorbent polysaccharide derivative obtained by oxidation and crosslinking of a polysaccharide selected from the group consisting of starch, amylose and amylopectin, .beta.-glucans, galactomannans, glucomannans and fructans, hydroxyethyl and hydroxypropyl derivatives thereof, and carboxyalkyl derivatives of starch, amylose, amylopectin, galactomannans and glucomannans, characterized in that at least 0.1 carbinol group per monosaccharide unit of the polysaccharide derivative has been oxidized to a carboxyl group, the total number of carboxyl groups per monosaccharide unit being 0.2-3.0, and the derivative results from reaction with 0.001-0.2 equivalent of crosslinking agent per monosaccharide unit.
