Abstract: Aqueous solutions or dispersions of copolymers obtainable by free-radical copolymerization of(a) from 20 to 90% by weight of at least one monoethylenically unsaturated C4-6-dicarboxylic acid or the anhydride thereof, as component A,(b) from 5 to 50% by weight of at least one olefin having 2 to 6 carbon atoms, as component B,(c) from 5 to 50% by weight of at least one hydrophobic comonomer from the group consisting of long-chain olefins, esters of long-chain alcohols with acrylic acid or methacrylic acid, long-chain amides of acrylic acid or methacrylic acid, and long-chain alkyl vinyl ethers, as component C,(d) from 0 to 40% by weight of further comonomers which can be copolymerized with the above monomers, as component D,where the sum of the amounts of components A, B, C and, if used, D is 100% by weight, followed by at least partial esterification or hydrolysis and neutralization and/or reaction of the carboxyl groups formed during the hydrolysis with bases, for treating leather and/or fur skins.

Abstract: PCT No. PCT/EP95/00418 Sec. 371 Date Aug. 15, 1996 Sec. 102(e) Date Aug. 15, 1996 PCT Filed Feb. 6, 1995 PCT Pub. No. WO95/22627 PCT Pub. Date Aug. 24, 1995Leather and skins are water repellent in aqueous emulsion in the presence of emulsifiers with polysiloxanes which are functionalized with carboxyl groups in a comb-like manner and in which the carboxyl groups are bonded to the polymer main chain via spacer groups in the form of linear or branched C2-C40-alkylene groups which may be interrupted by up to 8 non-neighboring oxygen atoms or groups of the formula -NR1-, CO- [sic] or -CO-NR1- and in addition may carry up to 5 carboxyl groups or carboxamido groups of the formula -CO-NR1R2-, where R1 and R2 are each hydrogen or C1-C4-alkyl, the spacer groups being bonded to the polymer main chain via a direct bond or via an oxygen atom or a group of the formula -NR1-, -CO-, -CO-NR1- or -CO-O-.

Abstract: Leathers and pelts are water-proofed in an aqueous emulsion in the presence of emulsifiers by comb-like carboxylated polysiloxanes in which the carboxyl groups are linked to the main polymer chain by spacer groups in the form of linear or branched C2- to C40-alkylene groups that may be separated by up to 8 non-adjacent oxygen atoms or groups having the formulas -NR -, CO- or -CO-NR and that may additionally bear up to 5 carboxyl groups or carboxylic acid amide groups having the formula -CO-NR R in which the residues R and R stand for hydrogen or C1- to C4-alkyl. The spacer groups are linked to the main polymer chain by a direct bond, an oxygen atom or a group having the formulas -NR -, -CO-, -CO-NR - or -CO-O-.
