Abstract (en)

[origin: US6652597B1] N-Vinyl-containing polymers obtainable by free-radically initiated polymerization of a monomer or monomer mixture of(A) from 5 to 100% by weight of an N-vinylamide or N-vinylamine,(B) from 0 to 95% by weight of monoethylenically unsaturated carboxylic acids having from 3 to 8 carbon atoms or their derivatives,(C) from 0 to 95% by weight of other N-vinyl and/or C-vinyl compounds and(D) from 0 to less than 10% by weight of other copolymerizable monomers,are useful in the form of aqueous solutions or dispersions as tanning materials for self-tanning, pretanning and cotanning of leather pelts and fur pelts and for retanning leather and fur.
