摘要

The present invention relates to a process for producing water-absorbing polymeric structures comprising the process steps: I. providing an untreated water-absorbing (Pu) polymeric structure with a retention determined according to the test method. described herein at least 35 g / g; and II. contacting this untreated water absorbing polymeric structure with a permeation enhancing agent. The invention further relates to water-absorbent polymeric structures obtainable by such a process, water-absorbent polymeric structures, a composite, a process for producing a composite, a composite obtainable by such a process, chemicals comprising water-absorbent polymeric structures or a as well as the use of water-absorbing polymeric structures or the composite in chemicals.
