ANIONIC POLYMER |
| abstract |
The invention relates to an anionic polysaccharide having superabsorbent characteristics, its polysaccharide being substituted by sulphate groups and the polysaccharide being cross-linked to a sufficient extent that it remains insoluble in water. The polysaccharide is preferably cellulose. The anionic polysaccharide can be made by a process which comprises (i) reacting a polysaccharide with a pyridine -SO3 complex in a solvent; followed by (ii) reacting with a cross-linking agent to provide a degree of cross-linking sufficient that the product remains insoluble in water. The sulphated polysaccharides show superabsorbent properties largely independent of pH over a wide range and can be used in applications where it is desired to absorb salt containing aqueous liquids, for example in diapers and catamenials. |
