    Abstract: The invention relates to a cross-linked, water-swellable polymer that contains polymerized into it moieties of a) water-soluble, monoethylenically unsaturated monomers, and b) 0.001 to 5 mole % based on the monomers a) of a cross-linking combination, b1) a first cross-linking agent with at least two (meth)acrylic ester moieties in the molecule and b2) a second cross-linking agent with at least two (meth)allyloxy moieties in the molecule, the molar ratio of b1) to b2) ranging from 0.7:1 to 10:1. The polymer according to the invention has a balanced property profile as regards absorptivity, gel strength, absorption speed and extractable components and can be advantageously produced by a continuous method.

    Abstract: Bead polymers are prepared by reverse suspension polymerization by a process in which an aqueous solution of water-soluble ethylenically unsaturated monomers are polymerized in an aliphatic hydrocarbon using an inorganic suspending agent based on a modified finely divided mineral and, in addition, from 0.1 to 5% by weight, based on the monomers used, of a nonionic surfactant, in the presence of a polymerization initiator, with the formation of a water-in-oil polymer suspension.
