摘要：
Copolymers which containa) from 50 to 90% by weight of C.sub.8 -C.sub.40 -alkyl methacrylates, vinyl esters of C.sub.8 -C.sub.40 -carboxylic acids or mixtures thereof andb) from 10 to 50% by weight of monoethylenically unsaturated C.sub.3 -C.sub.12 -carboxylic acids, monoethylenically unsaturated dicarboxylic anhydrides, monoesters or monoamides of monoethylenically unsaturated C.sub.4 -C.sub.12 -dicarboxylic acids, amides of C.sub.3 -C.sub.12 -monocarboxylic acids or mixtures thereofas copolymerized units and have molecular masses of from 500 to 30,000 are used in at least partially neutralized form in aqueous solution or dispersion for making leather and furs water repellent.
