摘要 |
The invention relates to a method for producing water-absorbent polymer entities, said method comprising the following steps: I. an untreated, water-absorbent polymer entity (Pu) with a retention of at least 35 g/g, defined according to the described test methods, is provided; and II. said water-absorbent, untreated polymer entity (Pu) is brought into contact with a permeability-increasing agent. The invention also relates to the water-absorbent polymer entities that can be obtained by said method, to water-absorbent polymer entities, a composite, a method for producing a composite, a composite that can be obtained by said method, chemical products containing water-absorbent polymer entities or a composite, and the use of water-absorbent polymer entities or the composite in chemical products. |
