    Abstract: Use of water-soluble or water-dispersible polymer by polymerization, comprising at least one alpha ,beta - ethylenic unsaturated compound, at least one of different monoethylenic unsaturated amide group containing compound, a cross linker, at least one monoethylenic unsaturated compound containing at least one group of 5-30C alkyl substituted group, 5-30C alkenyl, 5-8C cycloalkyl, aryl, aryl alkyl and hetaryl, and/or a reactive precursor, 0-30 wt.% of further different monoethylenic unsaturated compound and a polyether containing compound, for modification of the rheologic aqueous composition. Use of water-soluble or water-dispersible polymer by polymerization, comprising 99.99-10 wt.% of at least one alpha ,beta - ethylenic unsaturated compound with at least one cationogenic and/or cationic group per molecule, 0-90 wt.% of at least one of different monoethylenic unsaturated amide group containing compound, 0.01-5 wt.% of cross linker, 0-15 wt.% of at least one monoethylenic unsaturated compound containing at least one group of 5-30C alkyl substituted group, 5-30C alkenyl, 5-8C cycloalkyl, aryl, aryl alkyl and hetaryl, and/or a reactive precursor, 0-30 wt.% of further different monoethylenic unsaturated compound and 0-70 wt.% of a polyether containing compound, where the polymerization is carried out in the presence of less than 69 wt.% of cyclohexane and less than 12 wt.% of water, and the absence of carbon dioxide for modification of the rheologic aqueous composition. Independent claims are included for: (1) a water-soluble or water-dispersible polymer; and (2) a cosmetic or pharmaceutical agent comprising the water-soluble or water-dispersible polymer.

    Abstract: Copolymers prepared by a process comprising free-radical polymerizing: (a) more than 15 to 40% by weight of at least one monoethylenically unsaturated carboxylic acid; (b) 30 to less than 85% by weight of ethyl methacrylate; and (c) 0 to 50% by weight of at least one additional free-radically polymerizable monomer other than the at least one monoethylenically unsaturated carboxylic acid and ethyl methacrylate; wherein the total amount of (a), (b) and (c) equals 100% by weight; with the proviso that where the process comprises a solution polymerization, (a) consists of acrylic acid and methacrylic acid, and (c) is an ester of (meth)acrylic acid and an aliphatic C 8 -C 18 -alcohol, then the ester of (meth)acrylic acid and an aliphatic C 8 -C 18 -alcohol is not present in an amount of 5 to 40% by weight; and with the proviso that where (c) is selected from the group consisting of N-vinylpyrrolidone, N-vinylcaprolactam and mixtures thereof; then the N-vinylpyrrolidone, N-vinylcaprolactam or mixture thereof is present in an amount of less than 5% by weight.

    Abstract: The present invention relates to polymers obtainable by free-radical polymerization of a) 30 to 99% by weight of tert-butyl acrylate and/or tert-butyl methacrylate as monomer A, b) 1 to 70% by weight of acrylic acid and/or methacrylic acid as monomer B and c) 0 to 12% by weight of a free-radically copolymerizable monomer or a free-radically copolymerizable monomer mixture as monomer C, where at least one of the monomers C produces a homopolymer with a glass transition temperature of less than 30° C., with the proviso that the % by weight add up to 100, where the K value of the polymers is between 27 and 38 and where the polymerization is carried out in the presence of a regulator if the K value of the polymers is less than or equal to 35, and to the use of these polymers in preparations for, in particular, cosmetics and oral care and dental care.
