ABSTRACT:
A process for producing an absorbing polymer structure (Pa) including the steps of obtaining a treated absorbing polymer structure (Pb) by increasing the absorption under load at a load of 0.3 or 0.9 psi (AUL) compared to an untreated absorbing polymer structure (Pu) by a first treatment of an outer region of the untreated absorbing polymer structure (Pu) and reducing the AUL compared to the treated polymer structure (Pb) by a second treatment of an outer region of the treated absorbing polymer structure (Pb). Such absorbing polymer structure (Pa) may be used in a composite and may be used in foams, moulded articles, fibers, sheets, films, cables, sealing materials, liquid-absorbing hygiene articles, carriers for plant growth-regulating and fungal growth-regulating agents, packaging materials and soil additives or building materials.
