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: Surprisingly, it has been shown that the drawbacks of the previous state of the art, e.g. composition, purity and quality, and price variations of lanolin, can be avoided by substitution of crude, cleaned, and chemically modified wool fat and wool fat based mixtures by polyisobutene and polyisobutene derivatives as stuffing agents. A new stuffing agent for stuffing of skins and leather production including neutral and/or chemically modified native stuffing components (0-97 wt.%), one or more emulsifiers, and polyisobutene and/or polyisobutene derivatives of formula (I): R = a residue of formula (II), (III), or (IV); n = no value between 8 and 800; R = H or 2-8C alkyl, which can be substituted by one or two carboxyl or carboxylate groups, 1-6C alkoxycarbonyl with 1-6C in the alkoxy residue, alkylamino or dialkylamino-alkoxycarbonyl with a total of 1-6C in the alkylamino or dialkylamino groups, amidocarbonyl, cyan, phenyl, hydroxy, poly-lower alkoxy, lower acyloxy, or by the divalent group -O-CO-O- with which it forms a five-or six membered ring; R = R or with the exception of H, where the two R residues can be the same or different; R and R = H, OH, lower alkoxy, poly-lower alkoxy, or R or R = H and the other residue = sulfate (-OSO3H) or sulfone group (-SO3H), amino, alkylamino dialkylamino, with a total of 1-6C in the alkyamino or dialkylamino groups, or for groups of formula -O(CpH2p)COOH); p = 1-7, or their salts or 1-5C lower alkyl ester. The polymer has the formula (I), where R = a residue of formula (II) and R = H. Independent claims are included for: (1) a process for preparation of a polyisobutene stuffing composition by mixing at least one neutral and/or optionally a chemically modified, native stuffing component; and (2) a process for stuffing hides using polyisobutene directly as the stuffing material and/or a polyisobutene derivative in use singly or in combination with other stuffing materials, e.g. in the form of an aqueous emulsion.

Abstract: Producing aqueous copolymer dispersions with a water content of 30-99.5 wt.% comprises radical copolymerization of an ethylenically unsaturated dicarboxylic acid anhydride having 4-8 carbon atoms, an oligomer of an alkene having 3-10 carbon atoms and optionally an ethylenically unsaturated comonomer, optionally reacting the product with an alkoxylated alcohol (Ia) or alkoxylated amine (Ib), and adding water. Producing aqueous copolymer dispersions with a water content of 30-99.5 wt.% comprises radical copolymerization of an ethylenically unsaturated dicarboxylic acid anhydride having 4-8 carbon atoms, an oligomer of an alkene having 3-10 carbon atoms, where the oligomer has a molecular weight of 300-5000 or is produced by oligomerising at least 3 equivalents of the alkene, and optionally an ethylenically unsaturated comonomer, optionally reacting the product with an alkoxylated alcohol of formula (Ia) or alkoxylated amine of formula (Ib), and adding water. HO(A 1>O) nR 1> (Ia) H 2N(A 1>O) nR 1> (Ib) A 1>2-20C alkylene; R 1>1-30C alkyl, phenyl or H; n : 1-200. Independent claims are also included for: (1) aqueous copolymer dispersions produced as above; (2) treatment of fibrous substrates using the dispersions; (3) fibrous substrates treated as above; (4) copolymers produced by radical copolymerization of an anhydride, oligomer and optional comonomer as above, reaction with (Ia) or (Ib) and optional hydrolysis; (5) impregnating flat substrates with dispersions or copolymers as above.

Abstract: Use is claimed as a tanning agent (or an intermediate for a tanning agent) of a clay mineral which, after 30 minutes intensive stirring in water at 50degreesC, gives a laser and light scattering-determined ISO 13320-1 number average particle diameter (D) below 2 mu or a bimodal distribution of (i) 10-90 wt.% of a fraction with D below 0.5 mu and (ii) a coarser fraction of D below 5 mu. An Independent claim is also included for a formulation for use in chromium-free or chrome tanning comprising (a) a clay mineral as above and (b) one or more of an organic polymer, an aldehyde-, sulfone- , resin-, phenol- or vegetable-tanning agent, dubbing material, dye or pigment.
