Abstract
The invention relates to a surface post-crosslinked powder polymer, which is water-, or aqueous liquid-absorbing and produced from polymerised, optionally pre-crosslinked, partly neutralised, carboxyl-group-containing monomers. The invention further relates to a method for the post-treatment of said polymer and the use of a solution of a salt of an at least tri-valent cation for the regeneration of the gel-permeability of said polymer, when damaged by physical effects.
