| description | A highly permeable superabsorbent is prepared by a process comprisingpolymerizing an aqueous monomer solution comprisinga) at least one ethylenically unsaturated monomer which bears acid groups and is optionally at least partly in salt form,b) at least one crosslinker,c) at least one initiator,d) optionally one or more ethylenically unsaturated monomers copolymerizable with the monomers mentioned under a), ande) optionally one or more water-soluble polymers;drying the resulting polymer,optionally grinding the dried polymer and sieving the ground polymer,optionally surface postcrosslinking the dried and optionally ground and sieved polymer,wherein, after drying, grinding or sieving, and, if surface postcrosslinking is conducted, during or after this surface postcrosslinking, x-ray-amorphous aluminum hydroxide powder is added. |
