Abstract (en)
[origin: DE19546254A1] Copolymers of (A) 5 to 95 mol % of ethylenically unsaturated monocarboxylic acids or dicarboxylic acids with 3 to 10 C-atoms, their anhydrides, their alkali metal salts, alkaline earth metal salts or ammonium salts or mixtures thereof; (B) 5 to 95 mol % of ethylenically unsaturated acetals, cetals or orthocarboxylic acid esters of the general formula (I), in which the variables have the following meanings: R<1> to R<12> are, independently of each other, hydrogen or an organic radical and a to d are, independently of each other, 0 or 1; and (C) 0 to 70 mol % of other copolymerisable monomers. The invention relates to the use of aqueous solutions or dispersions of said copolymers or hydrolysis products or polymeric analogous reaction products of said copolymers as tanning agents for single tannage, pre-tannage and co-tannage of dehaired skins and hides, and retannage of leather and skins.
