SUPERABSORBER POST-RETICULATED ON THE SURFACE AND TREATED WITH A WATER SOLUBLE ALUMINIUM SALT AND ZINC OXIDE |
摘要 |
A water-absorbing polymer structure is disclosed, whose surface has been brought into contact with a combination of a metal salt and an oxide of a metal. The invention also relates to a process for treating the surface of water-absorbing polymer structures whereby the surface of water-absorbing polymer structures is brought into contact with a combination of a metal salt and an oxide of a metal at a temperature of from about 50 to about 300° C. The present invention further relates to the water-absorbing polymer structures obtainable by this process, a composite comprising a water-absorbing polymer structure and a substrate, chemical products such as foams and fibers comprising water-absorbing polymer structures or a composite, and the use of a combination of an oxide of a metal and of a metal salt for treatment of the surface of super-absorbing polymer structures. |
