Abstract:
The present invention relates to a water-absorbing particulate composition comprising water-absorbing polymer particulate structure comprising partly neutralized, crosslinked polyacrylate, a surface crosslinking agent and a compound of the structure I in which R1, R2, R3 and R4 can be identical or different and in each case represent a hydrogen atom, a halogen atom, a C1- to C4-hydrocarbon group or a hydroxyl group, R5 represents a hydrogen atom, a C1- to C4-hydrocarbon group or an acetyl group, n represents an integer chosen from the group consisting of 1, 2 or 3 and Mn+ represents an n-valent metal cation or an H+ cation. In addition, the present invention also relates to a process for the preparation of a water-absorbing composition, the water-absorbing composition obtainable by this process, a composite, a process for the production of a composite, the composite obtainable by this process, and products, such as hygiene articles.
