摘要：
The invention relates to a method for producing a water-absorbing polymer structure. Said method comprises the following steps: i) an untreated, water-absorbing polymer structure is provided that has a maximum neutralization rate of 70 mole percent; ii) the untreated, water-absorbing polymer structure is brought in contact with an acid component. The invention also relates to the water-absorbing polymer structures obtained using said method, water-absorbing polymer structures, a compound, a method for producing a compound, the compound obtained using said method, foams, molded articles, fibers, foils, films, cables, sealing materials, liquid-absorbing hygiene articles, carriers for plant growth and fungal growth regulators, packaging materials, soil additives, or construction materials, and the use of a water-absorbing polymer structure.
