    Abstract: Water-soluble copolymers which comprise, in copolymerized form, (a) 60 to 99% by weight of at least one monoethylenically unsaturated polyalkylene oxide monomer of the formula I H2C═CR1—X—YR2—OnR3  I  in which the variables have the following meanings: X is —CH2— or —C(O)—, if Y is —O—; is —C(O)—, if Y is —NH—; is —O— or —O—(CH2)4—, if Y is a chemical bond; Y is —O—, —NH— or a chemical bond; R1 is hydrogen or methyl; R2 is C2-C4-alkylene radicals, which may be identical or different and also linear or branched, but where at least 50% of the radicals R2 are ethylene; R3 is C1-C22-alkyl, phenyl, p-(C1-C12-alkyl)phenyl or hydrogen; n is an integer from 6 to 50, (b) 1 to 40% by weight of at least one nonquaternized dipolar monomer comprising at least one nitrogen atom, (c) 0 to 39% by weight of other nonionic monoethylenically unsaturated monomers and (d) 0 to 10% by weight of other anionic monoethylenically unsaturated monomers and have an average molecular weight Mw of from 2000 to 500 000 D, and the use of the copolymers as dispersants and sequestrants for pigmented materials, as additive for detergents, laundry pretreatment compositions, cleaners for hard surfaces, dentifrices and bodycare compositions, and as auxiliaries for textile processes, paper making and paper processing and deinking processes.

    Abstract: The invention relates to aqueous dispersions of water-soluble polymers of N-vinyl-carboxamides, which are substantially salt-free and comprise anionic polymeric stabilizers having a comb-like molecular structure, processes for the preparation of the dispersions in the presence of anionic polymeric stabilizers having a comb-like molecular structure and the use of the dispersions as retention aids or fixing agents in papermaking.

    Abstract: Preparation of leather involves treating unhaired hide, pickled unhaired hide or semi-finished leather with a polymer (A) obtained by copolymerization of: one or more of 3-8C monoethylenically unsaturated mono- or dicarboxylic acids or their anhydrides; vinyl aromatic compound(s); alkoxylated unsaturated ether(s) (I); and optionally further monoethylenically unsaturated monomers. The copolymers (A) are new. Preparation of leather involves treating unhaired hide, pickled unhaired hide or semi-finished leather with a polymer (A) obtained by copolymerization of: (1) one or more of 3-8C monoethylenically unsaturated mono- or dicarboxylic acids or their anhydrides, (2) vinyl aromatic compound(s), (3) alkoxylated unsaturated ether(s) of formula (I) and optionally (4) further monoethylenically unsaturated monomers. [Image] R 1>- R 5>H or Me; R 6>H, SO 3M, PO 3M 2, CHO, (1-20C) alkylcarbonyl or (6-14C) arylcarbonyl; M : alkali metal, NH 4+>or Me; n : 3-100; y : 0-10. Independent claims are included for: (a) the polymers (A) as new; (b) the preparation of (A); and (c) aqueous dispersions containing up to 50 wt. % (A).
