Zusammenfassung:	Cross-linked copolymers possessing high thickening and suspending properties obtainable by polymerization of monomeric systems comprising a) 10-97% of at least one unsaturated carboxylic acid, b) 0-80% of at least one alkyl ester of an unsaturated acid, c) 0.5-80% of an associative monomer, d) 0-20% of an unsaturated amide, e) 0.2-20% of a suitable cross-linking agent and f) 0-20% of an unsaturated sulfonic acid; processes for their preparation, which comprise polymerization by precipitation, suspension and solution polymerizations or emulsion polymerization; latexes comprising up to 50% or more of said copolymers; said cross-linked copolymers and said latexes whenever prepared by the above polymerization processes; their use as thickening agents of aqueous, or substantially aqueous systems; and the new cross-linking agents.
