    摘要: Re-moisturised, surface-crosslinked superabsorbents are produced using a process that comprises the steps of contacting a superabsorbent base polymer with an organic crosslinker and a polyvalent metal salt solution in the presence of an alcohol, heat-treating to produce a surface-crosslinked, dry superabsorbent and re-moisturising the surface-crosslinked dry superabsorbent.

    摘要: A process for preparing water-absorbing polymers by polymerizing a monomer solution comprising at least one ethylenically unsaturated, acid-bearing monomer which may be at least partly neutralized, from 0.01 to 0.5% by weight of at least one crosslinker based on the monomer, by polymerizing the monomer solution and aftertreating the resulting polymer with from 0.05 to 0.25% by weight of at least one postcrosslinker, based on the polymer, where the crosslinker is not a polyol, and from 0.05 to 0.5% by weight of at least one polyvalent cation based on the polymer.
