    摘要: Water-soluble or water-dispersible graft polymers which are obtainable by free-radical-initiated polymerization of (A) a monomer or monomer mixture comprising (a) from 20 to 100% by weight of acrylic acid or methacrylic acid or a mixture thereof or alkali metal, alkaline earth metal or ammonium salts thereof, (b) from 0 to 80% by weight of other monoethylenically unsaturated monomers which can be copolymerized with the monomers (a), and (c) from 0 to 5% by weight of monomers containing at least 2 ethylenically unsaturated, non-conjugated double bonds in the molecule, in the presence of proteins (B) in an A:B weight ratio of from (95 to 10):(5 to 90), are used as tanning agents for self-tanning, pretanning and assist tanning of pelts and skin pelts and for the retanning of leather and skin.
