WATER-ABSORBENT POLYMER STRUCTURE WITH IMPROVED PERMEABILITY AND ABSORPTION UNDER PRESSURE

摘要

The invention relates to a method for producing water-absorbent polymer structures, comprising the following steps: i) an untreated, water-absorbent polymer structure is provided; ii) the untreated, water-absorbent polymer structure is brought into contact with a salt comprising a divalent or higher-valent cation of a metal and at least one organic base as an anion. The invention also relates to water-absorbent polymer structures that can be obtained using said method, to water-absorbent polymers, to a composite containing a water-absorbent polymer structure and a substrate, to a method for producing a composite, to the composite obtained using said method, to chemical products such as foams, moulded bodies and fibres containing water-absorbent polymer structures or a composite, to the use of water-absorbent polymer structures or a composite in chemical products and to the use of a salt for treating the surface of water-absorbent polymer structures.
