摘要

O.Z. 0050/41109 Copolymers which contain a) from 50 to 90 % by weight of C8-C40-alkyl meth acrylates, vinyl esters of C8-C40-carboxylic acids or mixtures thereof and b) from 10 to 50 % by weight of monoethylenically unsaturated C3-C12-carboxylic acids, monoethylenically unsaturated dicarboxylic anhydrides, monoesters or monoamides of monoethylenically unsaturated C4-C12-dicarboxylic acids, amides of C3C12-monocarboxylic acids or mixtures thereof as copolymerized units and have molecular masses of from 500 to 30,000 are used in at least partially neutralized form in agueous solution or dispersion for making leather and furs water repellent.
