Abstract:
1. An absorbing polymer composition (Pa) obtained by a process comprising the following steps: preparing an absorbing polymer comprising the step of polymerizing (α1) 0.1 to 99.999 wt. % of polymerized, ethylenically unsaturated, acid group-containing monomers or their salts, or polymerized, ethylenically unsaturated monomers containing a protonated or quaternated nitrogen atom, or their mixtures; and (α2) 0.001 to 10 wt% of a crosslinking agent, resulting in an untreated dried absorbing polymer structure (Pu) having an outer region and an absorption under load (AUL) at a load of 0.3 psi (AUL preparing a treated absorbing polymer structure (Pb) comprising the steps of treating the outer region of the untreated absorbing polymer structure (Pu) wherein the (AUL
