    Abstract: Fibrous substrates are treated with (a) at least one oligomer of branched or straight-chain C 3 -C 10 -alkene having an average molecular weight M n of up to 1200 g/mol, (b) at least one emulsifier which is obtainable by copolymerization of (A) at least one ethylenically unsaturated dicarboxylic anhydride, derived from at least one dicarboxylic acid of 4 to 8 carbon atoms, (B) at least one oligomer of branched or straight-chain C 3 -C 10 -alkene, at least one oligomer having an average molecular weight M n of up to 1200 g/mol, (C) at least one alpha-olefin of up to 16 carbon atoms and (D) optionally at least one ethylenically unsaturated comonomer, and optionally reaction with (E) at least one compound of the formula I a, I b, I c or I d and, if appropriate, subsequent contact with water, where, in formulae I a to I d, A 1 are identical or different C 2 -C 20 -alkylene, R 1 is linear or branched C 1 -C 30 -alkyl, phenyl or hydrogen, and n is an integer from 1 to 200.

    Abstract: In a process for the production of leather, pelts, pickled pelts or semifinished products are treated with at least one polymer which is obtainable by copolymerization of at least one ethylenically unsaturated dicarboxylic anhydride (A), derived from at least one dicarboxylic acid of 4 to 8 carbon atoms, at least one vinylaromatic compound (B) and optionally at least one ethylenically unsaturated monomer (C) which differs from (A) and has a hetero atom, reaction with at least one compound (D) of the formula Ia or Ib at least 0.55 equivalent, based on (A), of (D) being used, and optionally hydrolysis with water or aqueous alkaline solution, where, in formulae Ia and Ib, the variables are defined as follows: A 1 are identical or different and are C 2 -C 6 -alkylene R 1 is linear or branched C 1 -C 20 -alkyl, and n is an integer from 6 to 200.

    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).
