<p>A water-absorbent starch product is made by a method in which an aqueous dispersion of starch, water, free-radical initiator and ethylenically unsaturated monomer, which monomer consists essentially of monomer having a boiling point of at least 100 DEG C, is simultaneously polymerised and dried at a temperature above 100 DEG C to provide a dry, water-absorbent starch product or a precursor thereof. Effective water-absorbent starch products, essentially free from water-soluble salts and free-radical initiator contaminants and containing a high level of functional water attractant groups, may be directly manufactured without the need for further refining or chemical modification. </p> |
