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.
