    Abstract: The use of copolymers containing a) from 60% to 99% by weight of at least one vinyllactam or N-vinylamine selected from the group consisting of N-vinylpyrrolidone, N-vinylpiperidone, N-vinylcaprolactam or N-vinylformamide, and b) from 1% to 40% by weight of at least one monomer of the general formula where b1) R 1 , R 2 , R 3 each denote oxygen, C 1 -C 4 -alkyl, C 6 -aryl, C 7 -C 10 -alkylaryl and R 4 denotes the general formula II X denotes oxygen, NH, NR (where R=R1) R 5 denotes C 1 -C 6 -alkyl, phenyl, A denotes OH, NH 2 , NR 2 (wheret R 2 =R1) R 6 , R 7 R 8 each denote hydrogen, C 1 -C 4 -alkyl n denotes an integer between 1 and 4 B, F each denote C, N D denotes C 1 -C 4 -alkyl, O, NH p denotes an integer between 0 and 15 E denotes N, O l, m each denote 0 or 1 R 9 , R 10 , R 11 each denote hydrogen, C 1 -C 4 -alkyl, C 6 -C 10 -aryl, C 7 -C 10 -alkylaryl and s, q each denote an integer between 0 and 2. For E=nitrogen the s+q sum is equal to 1 or 2. For E=oxygen the s+q sum is equal to zero. For E=nitrogen and s+q=2 the counterions needed for charge neutrality are selected from elements of groups 1, 2 or 13 with the proviso that there is one element of group 1 per R4 radical when a group 1 element is selected, one element of group 2 per two R4 radicals when a group 2 element is selected and one element of group 13 per three R4 radicals when a group 13 element is selected. b2) R 1 , R 2 , R 3 each denote hydrogen, C 1 -C 4 -alkyl, C 6 -aryl, C 7 -C 10 -alkylaryl or a radical of the general formula III R 4 denotes a radical of the general formula III R 6 , R 7 each denote hydrogen, C 1 -C 4 -alkyl, C 6 -aryl, C 7 -C 10 -alkylaryl X denotes O, NH, NR (where R=R6) R5 denotes C 1 -C 10 -alkyl, C 6 -C 10 -aryl, C 7 -C 14 -alkylaryl n denotes an integer between 0 and 15 Y denotes O, N R6, R7 each denote hydrogen, C 1 -C 4 -alkyl, C 6 -aryl, C 7 -C 10 -alkylaryl p, q each denote an integer between 0 and 2 with the proviso that at least one of R 1 , R 2 , R 3 and R 4 but not more than two denote the general formula III. b3) R 1 , R 2 , R 3 each denote hydrogen, C 1 -C 4 -alkyl, C 6 -aryl, C 7 -C 10 -alkylaryl R 4 denotes a radical of the general formula IV R 5 denotes C 1 -C 8 -alkyl n denotes an integer between 0 and 4 m, l each denote 0 or 1 R 6 denotes C 1 -C 4 -alkyl R 7 denotes hydrogen, C 1 -C 4 -alkyl and X N(R1)(R2) or halogen. b4) R 1 , R 2 , R 3 each denote hydrogen, C 1 -C 4 -alkyl, C 6 -aryl, C 7 -C 10 -alkylaryl R 4 denotes a radical of the general formula V X, Y each denote O, N, S R 5 , R 6 each denote C 1 -C 4 -alkyl, C 1 -C 4 -alkenyl l, m each denote an integer between 0 and 4 n denotes an integer between 0 and 2 R 7 denotes hydrogen, C 1 -C 4 -alkyl Z denotes sulfate, hydrogensulfate, chloride, bromide, iodide, phosphate, hydrogenphosphate, dihydrogenphosphate p denotes 0, 1/3, ½, 1 and q denotes an integer between 0 and 3. b5) R 1 , R 2 , R 3 each denote hydrogen, C 1 -C 4 -alkyl, C 6 -aryl, C 7 -C 10 -alkylaryl, or a radical of the general formula VI R 4 denotes a radical of the general formula VI R 5 , R 7 , R 8 , R 11 each denote C 1 -C 6 -alkyl, C 6 -aryl, C 7 -C 10 -alkylaryl R 6 , R 12 each denote hydrogen, C 1 -C 4 -alkyl, C 6 -aryl R 9 , R 10 each denote hydrogen, C 1 -C 4 -alkyl, C 6 -aryl, C 7 -C 10 -alkylaryl X denotes O E, F, Y, D each denote O, N, S M denotes an element of group 1, 2 or 13 of the periodic table a, k, l, s each denote 0 or 1 m, n, r, w each denote an integer between 0 and 10 o denotes an integer between 0 and 3 p denotes an integer between 0 and 20 q, t, u, v, z each denote an integer between 0 and 2 x denotes 0, 1/3, ½, 1 and y an integer between 1 and 3 with the proviso that at least one of R 1 , R 2 , R 3 and R 4 but not more than 2 denote the general formula VI, in conjunction with c) optionally one or more hydrophilic polymers C or mixtures thereof d) and optionally also further polymers D and mixtures thereof for producing membranes.
