Abstract
A process for producing a polysaccharide superabsorbent particulate including the process steps of bringing into contact a polysaccharide with a polyphosphate or a polyphosphoric acid as crosslinking agent in the presence of water to form a polysaccharide gel drying the polysaccharide gel, comminuting the dried polysaccharide gel to form polysaccharide superabsorbent polymer particles, coating the particles with a polyphosphate or polyphosphoric acid, crosslinking the coated particles, and surface treating the particulate with a metal multivalent salt or an acid. The invention further relates to a polysaccharide superabsorbent polymer particulate obtainable by this process, a water-absorbent polysaccharide, a composite, a process for producing a composite, a composite produced by this process, the use of the polysaccharide superabsorbent particulates or of the composites as well as the use of polyphosphates.
