O.Z. 0050/41004 Abstract of the Disclosure: Copolymers which are obtain- able by free radical copolymerization of (a) C8-C40- monoolefins with (b) ethylenically unsaturated C4-C8- dicarboxylic anhydrides by mass polymerization at from 80 to 300°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 com- plete 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 rendering leathers and skins water-repellent.
