CA 2122245

The present invention discloses the use of polymers which have built-in by polymerization 20 to 70%-wt. of a hydrophobic monomer selected from long-chain alpha-olefins, long-chain alkyl(meth)acrylates, vinyl esters of long-chain carboxylic acids, long-chain vinyl ethers, or mixtures of these monomers, 1 to 60%-wt. of a monomer with a specific polysiloxane group, and 20 to 35%-wt. water-soluble, unsaturated acids, unsaturated C4 - C6 dicarboxylic anhydrides, semi-esters or semi-amides of unsaturated C4 - C6 di-carboxylic acids, or mixtures of these monomers, in partially newtralized form as aqueous solution or dispersion, for softening, fat-liquoring and greasing, or hydrophobing leathers and furs.

La présente invention porte sur l'utilisation de polymères qui possèdent, par polymérisation, 20 à 70 % en poids d'un monomère hydrophobe choisi parmi des alpha-oléfines à longue chaîne, des alkyl(méth)acrylates à longue chaîne, des esters vinyliques d'acides carboxyliques à longue chaîne, des éthers vinyliques à longue chaîne ou des mélanges de ces monomères, 1 à 60 % en poids d'un monomère portant un groupe polysiloxane spécifique, et 20 à 35 % en poids d'acides insaturés, hydrosolubles, d'anhydrides dicarboxyliques en C4-C6 insaturés, de mono-esters ou mono-amides d'acides dicarboxyliques en C4-C6 insaturés, ou des mélanges de ces monomères, dans une forme partiellement neutralisée sous forme de solution ou de dispersion aqueuse; ces polymères sont utiles pour l'assouplissement, la nourriture en bain et le graissage, ou l'hydrofugation des cuirs et des fourrures.
