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/EP93/00791 Sec. 371 Date Sep. 15, 1994 Sec. 102(e) Date Sep. 15, 1994 PCT Filed Apr. 1, 1993 PCT Pub. No. WO93/21196 PCT Pub. Date Oct. 28, 1993The preparation of alkyl glycosides by reaction of aqueous glycoses having a water content of 10-80% by weight with aliphatic primary alcohols having from 5 to 30 C atoms is described, in which (a) the alcohols and the glycoses are employed in a molar ratio of 2:1 to 10:1, (b) 0.1-5% by weight, based on the amount of the glycoses employed, of the acidic form of an anionic surfactant is used as the acidic catalyst having emulsifying properties, (c) 1-30% by weight, based on the amount of the glycoses employed, of alkyl glycosides is used as a further emulsifier, (d) the aqueous glycose is preheated to 50 DEG -90 DEG C. and the preheated aqueous solution of the glycose is metered with effective mixing into the reaction mixture of alcohol, acidic catalyst and emulsifier in such a manner that an emulsion is formed, (e) the reaction is carried out at from 100 DEG to 150 DEG C. and from 10 to 100 mbar, the water introduced into the reaction mixture and the water formed by the reaction being continuously removed by distillation, (f) after the reaction has ended, the acidic catalyst is neutralized by addition of a base such that the resulting mixture has a pH of 8-10, then (g) the excess alcohol is removed by distillation at from 0.01 to 10 mbar down to a residual content of less than 5% by weight, based on the amount of alkyl glycoside present, and (h) the reaction mixture is bleached at pH 8-10 after conversion into an aqueous paste having a content of from 30 to 70% by weight of alkyl glycoside using a compound eliminating active oxygen.

Abstract: Copolymers of hydroxyalkyl vinyl ethers are obtainable by cationic or free radical copolymerization of (a) from 99 to 1% by weight of a hydroxyalkyl vinyl ether, (b) from 1 to 99% by weight of an adduct of a C2-C4- alkylene oxide with a hydroxyalkyl vinyl ether and (c) from 0 to 98% by weight of other copolymerizable monomers, and the stated copolymer and hydroxyalkyl vinyl ethers polymerized by cationic or free radical polymerization, which contain the monomers (a) or (b) as sole monomers or as a mixture with other copolymerizable monomers in the form of polymerized units, are used as additives for detergents and cleaning agents in amounts of from 0.1 to 50% by weight.
