摘要：
Finishers for texthes, leather, paper and mineral substrates consisting of fluorine-containing copolymers and aqueous dispersions prepared therefrom are characterized by the following percentages by weight of the comonomers, relative to the total weight of the copolymers:a) 60 to 90% by weight of perfluoroalkyl-containing (meth)acrylates of the formulaC.sub.n F.sub.2n+1 --X--0--CO--CR.sup.1 .dbd.CH.sub.2 (I),b) 1 to 35% by weight of monomers of the formulaCH.sub.2 .dbd.CR.sup.4 --COO--R.sup.5 (II)and/or styrene, acrylonitrile, vinyl acetate or vinyl propionate,c) 4 to 25% by weight of monomers of the formula ##STR1## d) 1 to 15% by weight of monomers of the formulaCH.sub.2 .dbd.CR.sup.11 --COOCH.sub.2 CH.sub.2 --N(R.sup.9,R.sup.10)(IVa)or[CH.sub.2 .dbd.CR.sup.11 --COO--CH.sub.2 CH.sub.2 --N(R.sup.9,R.sup.10,R.sup.12)].sup..sym.
