<p>A biodegradable, highly water-absorbing polymer based on starch or derivatives thereof is described, wherein the starch has not been chemically modified or only to a degree of substitution of below 0.2, and has a water-absorbing power of at least 10 times its own weight, half of the water absorption being attained within three minutes.</p><p>A process for producing such a water-absorbing polymer is also described, the process comprising partially gelatinising starch and optionally crosslinking it in such a way that an open structure is obtained and fixated.</p> |
