Abstract: A highly permeable superabsorbent is prepared by a process comprising
polymerizing an aqueous monomer solution comprising
a) 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), and
e) 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,
