    Abstract: Water-soluble copolymers having a K value of from 15 to 120 (determined according to H. Fikentscher in an aqueous solution of their sodium salt at 25.degree.C, a pH of 7 and a polymer concentration of the Na salt of 1% by weight) contain, in polymerized form, a) not less than 80 mol % of one or more monoethylenically unsaturated C3-C6-monocarboxylic acids, b) from 0.5 to 20 mol % of a comonomer which possesses two or more ethylenically unsaturated, non-conjugated double bonds and one or more -CO-OX groups and/or their salt with an alkali metal, ammonium or alkaline earth metal base, and, if required, c) not more than 10 mol % of one or more comonomers which differ from b) and possess two or more ethylenically unsaturated, non-conjugated double bonds, and the said copolymers are prepared by copolymerization of the monomers a), b) and, if required, c) in aqueous solution and are used for coating seed.

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.
