WATER-ABSORBING POLYMERIC PARTICLES AND METHOD FOR THE PRODUCTION THEREOF |
摘要 |
<p>The present invention relates to a water absorbing material obtainable by a process comprising the steps of bringing particles of a non surface-crosslinked water-absorbing polymer in contact with a) at least one postcrosslinker, b) 10-1000 ppm, based on the non surface-crosslinked water-absorbing polymer, of at least one Nitrogen-containing water-soluble polymer of which the Nitrogen can be protonated, and c) at least one hydrophobic polymer and heat-treating the particles thus obtained at a temperature in the range from 120° C. to 300° C. and a method for the production thereof.</p> |
