    摘要: The invention refers to absorbent structures for use in an absorbent article, the absorbent structure comprising a water absorbing material. The water absorbing material is obtainable by a process comprising the steps of bringing particles of a non surface-crosslinked water-absorbing polymer in contact with at least one post-crosslinker, at least one water-insoluble metal phosphate, and at least one further ingredient. The at least one ingredient is selected from at least one Nitrogen-containing water-soluble polymer, and at least one hydrophobic polymer. The particles are heat-treated at a temperature in the range from 120° C. to 300° C.
