Abstract (en)
[origin: US2007107135A1] Leathers are produced by a process wherein pelts, pickled pelts or semifinished products are treated with at least one polymer which is obtainable by copolymerizing (A) at least one ethylenically unsaturated mono- or dicarboxylic acid of 3 to 8 carbon atoms or at least one anhydride derived from a mono- or dicarboxylic acid of 3 to 8 carbon atoms, (B) at least one vinylaromatic compound, (C) at least one alkoxylated unsaturated ether of the formula I (D) optionally further monoethylenically unsaturated monomers, where, in formula 1, the variables are defined as follows: R<SUP>1</SUP>, R<SUP>2 </SUP>and R<SUP>3 </SUP>are identical or different and are selected from C<SUB>1</SUB>-C<SUB>4</SUB>-alkyl and hydrogen; R<SUP>4 </SUP>and R<SUP>5 </SUP>are in each case identical or different and are selected from C<SUB>1</SUB>-C<SUB>4</SUB>-alkyl and hydrogen; R<SUP>6 </SUP>is selected from hydrogen, SO<SUB>3</SUB>M, PO<SUB>3</SUB>M<SUB>2</SUB>, C<SUB>1</SUB>-C<SUB>30</SUB>-alkyl, CO-H (formyl), CO-C<SUB>1</SUB>-C<SUB>20</SUB>-alkyl and CO-C<SUB>6</SUB>-C<SUB>14</SUB>-aryl, M is an alkali metal or NH<SUB>4</SUB><SUP>+</SUP> or CH<SUB>3</SUB>, n is an integer from 3 to 100 and y is an integer from 0 to 10.
