PCT No. PCT/EP93/00354 Sec. 371 Date Aug. 26, 1994 Sec. 102(e) Date Aug. 26, 1994 PCT Filed Feb. 15, 1993 PCT Pub. No. WO93/17130 PCT Pub. Date Sep. 2, 1993.Products useful for fatliquoring and filling leather and fur skins are obtained on reacting A) homo- or copolymers based on monoethylenically unsaturated dicarboxylic anhydrides and obtainable by free-radically initiated polymerization of a) from 30 to 100 mol % of one or more monoethylenically unsaturated dicarboxylic anhydrides of from 4 to 10 carbon atoms, b) from 0 to 70 mol % of one or more aromatic vinyl compounds of the general formula I <IMAGE> I where R1, R2 and R3 are each hydrogen, methyl or ethyl and k is 1 or 2, (c) from 0 to 70 mol % of one or more vinyl esters of C1- to C8-carboxylic acids, (d) from 0 to 50 mol % of one or more C2- to C6-olefins, and (e) from 0 to 30 mol % of one or more monoethylenically unsaturated C3- to C5-carboxylic acids, which mixture of monomers (a) to (e) may additionally contain up to 10% by weight of further copolymerizable monomers, with B) amines of the general formula R4R5NH, where R4 is hydrogen, C1- to C20-alkyl, C5- to C8-cycloalkyl or C2- to C4-hydroxyalkyl and R5 is C6- to C30-alkyl, C6- to C30-alkenyl, C5- to C8-cycloalkyl or C2- to C4-hydroxyalkyl, or alcohols of the general formula R6-O-(CmH2mO)p-(CnH2nO)q-H, where R6 is C1- to C30-alkyl, C2- to C30-alkenyl, C5- to C8-cycloalkyl or-if p+q>0-hydrogen, m and n are each from 2 to 4 and p and q are each from 0 to 50, or mixtures of such amines and alcohols.
