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).

Abstract: The invention relates to a mixture comprising a surfactant and a cosurfactant, the cosurfactant being an amphiphilic polymer having one or more hydrophobic subunits (A) and one or more hydrophilic subunits (B), wherein one or more hydrophobic subunits (A) have been formed on the basis of a polyisobutene block whose polyisobutene macromolecules have terminal double bonds to an extent of at least 50 mol %.
