Abstract: The invention relates to a composition comprising (α) at least one water-soluble polymer based on (a) 5 to 40 wt % of at least one monomer of the formula (I) and (b) 5 to 95 wt % of at least one monomer (b) which comprises acid groups and is different from monomer (a), and (β) at least one associative thickener. Further disclosed is a mixture comprising an inorganic binder and also the composition of the invention. A further aspect of the present invention is the use of the composition of the invention as a rheological additive.

Abstract: The present invention relates to coated polymer particles comprising a water-swellable polymer core and an essentially continuous coating encapsulating the core. The coating comprises an oxide, hydroxide or oxide hydrate of silicon, aluminum, zirconium, tin or titanium. The polymer particles do not show instantaneous swelling, when contacted with water or a water-containing liquid, but show delayed water absorption after an appropriate period of time. The coated polymer particles may be used in oil fields, in mining, for construction chemical compositions or as carrier for active substances. The coated polymer particles are prepared by a suspension coating process or a fluidized bed coating process.

Abstract: The present invention relates to a composition comprising (α) at least one inorganic binder and (β) at least one water-soluble copolymer based on (a) 0.1 to 20 wt % of at least one monomer of the formula (I) and (b) 25 to 99.9 wt % of at least one hydrophilic monomer (b) which is different from monomer (a), where the at least one copolymer has a molar mass average M of 1 500 000 to 30 000 000 g/mol. Furthermore, a process for producing this composition is disclosed. A further aspect of the present invention is the use of the copolymer of component (β) as rheological additive in a composition of the invention.
