Use of copolymers having polysiloxane units in the treatment of leather
and furs
摘要:
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 C.sub.4 -C.sub.6 dicarboxylic anhydrides, semi-esters or semi-amides of unsaturated C.sub.4 -C.sub.6 dicarboxylic acids, or mixtures of these monomers, in partially neutralized form as aqueous solution or dispersion, for softening, fat-liquoring and greasing, or hydrophobing leathers and furs.
