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: PCT No. PCT/EP90/01283 Sec. 371 Date Feb. 10, 1992 Sec. 102(e) Date Feb. 10, 1992 PCT Filed Aug. 6, 1990 PCT Pub. No. WO91/02094 PCT Pub. Date Feb. 21, 1991.Copolymers which are obtainable by free radical copolymerization of (a) C8-C40-alkyl vinyl ethers, if necessary as a mixture with not more than 50 mol % of C8-C40-monoolefins, with (b) ethylenically unsaturated C4-C8-dicarboxylic anhydrides at from 80 degrees to 300 degrees C. to give copolymers having molecular weights of from 500 to 20,000 g/mol, subsequent solvolysis of the anhydride groups of the copolymers and partial or complete neutralization of the carboxyl groups formed during the solvolysis, in an aqueous medium by means of a base, and which are present in the form of aqueous dispersions or solutions, are used as agents for imparting water repellency to leathers and skins.
