Abstract: The present invention relates to precipitation polymers which comprise, in copolymerized form, 80 to 99.9% by weight of at least one nonionic water-soluble monomer a) and 0.1 to 20% by weight of a monomer b) carrying amide or urea groups. The invention further relates to the use of these polymers as rheology modifiers for in particular aqueous compositions and as rheology-modifying setting agents in hair cosmetics. The invention further relates to aqueous compositions comprising these polymers.

Abstract: The present invention relates to new anionic associative rheology modifiers, their manufacture and application.

Abstract: The present invention relates to precipitation polymers obtainable by polymerization of a monomer mixture which comprises 30 to 99% by weight of at least one nonionic water-soluble monomer a) and at least one monomer b) different from a) selected from i) monomers carrying at least one hydroxyl group, ii) anionic monomers and iii) mixtures of i) and ii), if appropriate a monomer c) carrying at least one amino group, if appropriate further monomers, where the total amount of a), b), c) and d) is 100% by weight and where the monomer mixture, based on the total amount of a), b), c) and d), comprises less than 0.1% by weight of a monomer with at least 2 free-radically polymerizable double bonds per molecule. The invention furthermore relates to the use of these polymers as rheology modifiers for aqueous compositions, to aqueous compositions comprising these polymers and to the use of the polymers for thickening cosmetic and pharmaceutical preparations.
