Abstract: The invention relates to a process for tanning leather by using compounds of the general formula I where m is 0 or 1 and the radicals R are independently of each other C1-C18-alkyl, which may be substituted by hydroxyl or carboxyl and/or interrupted by oxygen atoms, or else one of the radicals R is a radical of the formula where R is alkylene, which may be substituted by hydroxyl and/or interrupted by oxygen atoms.

Abstract: The invention relates to the hydrophobization of leather and fur skins by the application of copolymers based on long chain alkyl vinyl ethers and the anhydrides of ethylenically unsaturated dicarboxylic acids, which comprises treating the leather or skin which is to be rendered hydrophobic with a solution or aqueous dispersion of copolymer obtained by the free radical copolymerization of a) C8-C40 alkyl vinyl ethers or mixtures of C8-C40 alkyl vinyl ethers with 50% in mols of C8-C40 monoolefins and b) anhydrides of ethylenically unsaturated C8-C40 dicarboxylic acids having molecular masses between 500 and 20,000 grams/mol, subsequent solvolysis of the anhydride groups of the copolymers, and at least partial neutralization of the carboxyl groups resulting from solvolysis.

Abstract: Use of copolymers obtainable by free-radical copolymerisation of (a) C8-C40-monoolefins with (b) ethylenically unsaturated C4-C8-dicarboxylic anhydrides in the manner of a mass polymerisation at from 80 to 300 DEG C to form copolymers having molecular weights of from 500 to 20,000 g/mol, subsequent solvolysis of the anhydride groups of the copolymers and at least partial neutralisation in an aqueous medium with bases of the carboxyl groups formed in the course of the solvolysis and which are present in the form of aqueous dispersions or solutions, as agents for waterproofing leathers and pelt furs.

Abstract: 1485737 Copolymers of tetrahydrofuran BASF AG 15 Jan 1975 [16 Jan 1974] 1698/75 Heading C3R [Also in Division D1] Polyalkylene oxide adducts have the general formula R-X where R is the radical after removal of oxygen linked active hydrogen atoms of a C 8-22 alcohol or carboxylic acid or an oxyalkylation product thereof with 1-20 moles of ethylene oxide and/or propylene oxide; X is the radical of a copolymer of ethylene oxide and/or propylene oxide and tetrahydrofuran. The total amount of alkylene oxide units in R-X is 60-95% by wt. and the molar ratio of units derived from ethylene oxide and/or propylene oxide to units derived from tetrahydrofuran is 1 : 0À5 to 1 : 3. Typical examples are derived from oleic acid : ethylene oxide: tetrahydrofuran in weight ratios 1 : (1À5-2À5): (1À5-3). Uses.-Emulsifiers in the pigment dyeing of textiles.
