Abstract: A copolymer which comprises, in copolymerized form, (A) 60 to 99% by weight of at least one monoethylenically unsaturated polyalkylene oxide monomer of the formula I (I) in which the variables have the following meanings: X is -CH2- or -CO-, if Y is -O-; is -CO-, if Y is -NH-; Y is -O- or −NH-; R1 is hydrogen or methyl; R2 are identical or different C2 -C6-alkylene radicals, which may be arranged blockwise or randomly; R3 is hydrogen or C1-C4-alkyl; n is an integer from 25 to 75, (B) 1 to 40% by weight of at least one quaternized nitrogen-containing monoethylenically unsaturated monomer selected from the group consisting of monomers of formula IIa to IId (IIa - IId) in which the variables have the following meanings: R is C1-C4-alkyl or benzyl; R' is hydrogen or methyl; Y is -O- or -NH-; A is C1-C6-alkylene; X– is halide, C1-C4-alkyl sulfate, C1-C4-alkylsulfonate and C1-C4-alkyl carbonate, (C) 0 to 10% by weight of anionic monoethylenically unsaturated monomers, and (D) 0 to 30% by weight of other nonionic monoethylenically unsaturatedmonomers and has an average molecular weight Mw of > 100,000.
