PF 60027 54 Water-absorbing polymeric particles and method for the production thereof Abstract The present invention relates to a water absorbing material obtainable by a process 5 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 10 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 15 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. 20The 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.Linvention concerne un matériau absorbant leau pouvant être obtenu au moyen dun procédé consistant à amener des particules de polymère absorbant leau à surface réticulée en contact avec : a) au moins un agent de post-réticulation, b) 0,1 - 1,0% en poids dau moins un phosphate métallique insoluble dans leau par rapport au polymère absorbant leau à surface réticulée, et au moins un autre ingrédient sélectionné dans le groupe formé par c) au moins un polymère soluble dans leau contenant de lazote, cette dernière pouvant être pr
