Abstract

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 post-crosslinker, b) 0.1 - 1.0 wt.% of at least one water-insoluble metal phosphate, based on the non surface-crosslinked water-absorbing polymer, and at least one further ingredient selected from c) at least one Nitrogen-containing water-soluble polymer of which the Nitrogen can be protonated, and d) 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.
