Claim:
1. A water-absorbing edge-modified-clay linked polycarboxylic acid and/or polycarboxylate polymer, obtainable by a polymerization reaction comprising the steps of: a) obtaining an aqueous polymerization reaction liquid, comprising (i) homogeneously dispersed therein, clay platelets with opposing basal platelet surfaces and platelet edges; and (ii) dissolved or homogeneously dispersed therein, polymerizable monomers comprising a carboxylic acid group and/or carboxylate group, and/or polymerizable oligomers of one or more of the monomers; b) initiating the polymerization of the monomers and/or oligomers in the liquid of step a);
