    Abstract: A copolymer obtainable by free-radical polymerization ofA) 50-99.99% by weight of an olefinically unsaturated C3-C5 monocarboxylic acid, of an olefinically unsaturated C4-C8 dicarboxylic acid or the anhydride thereof or a mixture of such carboxylic acids or anhydrides withB) 0.01-50% by weight of an olefinically unsaturated quaternary ammonium compound of the formula I or II whereR1 is C6-C20-alkyl, C6-C20-alkenyl, C5-C8-cycloalkyl, phenyl, phenyl(C1-C12-alkyl) or (C1-C12-alkyl)phenyl,R2 is hydrogen, methyl or phenyl,R3 and R4 are each H or C1-C4-alkyl,X is halogen, C1-C4-alkoxysulfonyloxy or C1-C4-alkanesulfonate, it also being possible for the latter to occur as R3 or R4 with the formation of a betaine structure,Y is O or NH, andA is C1-C6-alkylene, or a mixture of such ammonium compounds,C) 0 to 49.99% by weight of an acrylate or methacrylate of the formula III where R1, R2 and Y have the abovementioned meanings, R5 is hydrogen, methyl or ethyl, and n is a number from 0 to 25,D) 0-49.99% by weight of other copolymerizable monomers andE) 0-5% by weight of one or more compounds with at least two olefinically unsaturated groups in the molecule as crosslinker. The copolymers are suitable as thickeners and dispersants, especially in cosmetic compositions.

    Abstract: Polymers of ethylenically unsaturated compounds containing at least one covalently bonded N atom in the molecule, polymerised in the presence of monosaccharides, oligosaccharides, polysaccharides or derivatives thereof, obtainable by free-radical-initiated copolymerisation of (A) monomers or monomer mixtures from the group consisting of (a) N-vinylimidazoles which are substituted on the heterocyclic ring by up to three C1- to C12-alkyl radicals and can be present in N-quaternary form or in salt form, (b) five- to eight-membered N-vinyllactams which can be substituted on the ring by up to three C1- to C12-alkyl radicals, (c) dialkylaminoalkyl acrylates or methacrylates which have a total of up to 30 C atoms in the dialkylaminoalkyl radical and can be present in N-quaternary form or in salt form, (d) N-(dialkylaminoalkyl)acrylamide or N-(dialkylaminoalkyl)methacrylamide which has a total of up to 30 C atoms in the dialkylaminoalkyl radical and can be present in N-quaternary form or in salt form, and (e) diallyl-C1- to C12-alkylamines or salts thereof or diallyldi(C1- to C12-alkyl) ammonium compounds, where as further comonomers to (A) additionally (f) monoethylenically unsaturated C3- to C10-carboxylic acids and alkali metal salts, alkaline earth metal salts or ammonium salts thereof, (g) monoethylenically unsaturated C3- to C10-carboxylic acid esters and (h) small amounts of compounds containing at least two ethylenically unsaturated, non-conjugated double bonds in the molecule can be present, in the presence of (B) monosaccharides, oligosaccharides, polysaccharides, thermally or mechanically treated, oxidatively, hydrolytically or enzymatically degraded polysaccharides, oxidised, hydrolytically or enzymatically degraded polysaccharides, chemically modified mono-, oligo- and polysaccharides or mixtures of the aforementioned compounds (B) in the ratio by weight (A):(B) of (95 to 20):(5 to 80). The polymers are suitable for use as film-forming conditioners in cosmetic preparations and as stabilisers for perfumes and perfume oils.
