Abstract: The invention relates to a process for producing polymer composites suitable for absorbing and storing aqueous liquids, to the polymer composites obtainable by this process, and to the use of the polymer composites. The process comprises free-radical polymerization of a monomer composition M comprising 50 to 100% by weight, based on the total amount of monomers A and B, of at least one monomer A having one ethylenic double bond and at least one neutralizable acid group, 0 to 50% by weight of optionally one or more comonomers B which are different than the monomers A and have one ethylenic double bond, and 1 to 10% by weight, based on the total amount of monomers A and B, of at least one crosslinker C.
