| titleOfInvention | Method for the production of leather and semifinished products, and formulations that are suitable therefor |
| abstract | The invention relates to a method for producing semifinished products or leather by treating pelt, pickled pelt, or semifinished products with (a) at least one phyllosilicate and (b) at least one copolymer obtained by copolymerizing at least one ethylenically unsaturated dicarboxylic acid anhydride (A) that is derived from at least one dicarboxylic acid comprising 4 to 8 C atoms, at least one vinyl aromatic compound (B1) or at least one oligomer (B2) of branched or linear C2-C10 alkene, at least one oligomer being provided with an average molecular weight Mn ranging between 300 and 5000 g/mole or being obtained by oligomerizing at least 3 equivalents of C2-C10 alkene, and at least one optional ethylenically unsaturated monomer (C) which is different from (A) and comprises at least one heteroatom, and reacting the same with at least one compound (D) of general formula (Ia) or (Ib), and optionally hydrolyzing the same with water or aqueous alkaline solution. The variables in formula (Ia) and (Ib) are defined as follows: A<1 >is identical or different and represents C2-C6 alkylene, R<1> represents linear or branched C1-C20 alkyl, and n represents an integer between 1 and 200. |
