    Abstract: Water-soluble hydrophobically, associating copolymer comprises (in wt.%): (a) monoethylenically unsaturated hydrophobically associated monomers (0.1-20); and (b) at least one of them different, monoethylenically unsaturated hydrophilic monomers (25-99.9), based on the total amount of all monomers in the copolymer, where at least one of the monomer is a hydrocarbon (I). Water-soluble hydrophobically, associating copolymer comprises (in wt.%): (a) monoethylenically unsaturated hydrophobically associated monomers (0.1-20); and (b) at least one of them different, monoethylenically unsaturated hydrophilic monomer (25-99.9), based on the total amount of all monomers in the copolymer, where at least one of the monomer is a hydrocarbon of formula (H 2C=C(R 1>)-R 4>-O-(-CH 2-CH(R 2>)-O-) k-(-CH 2-CH(R 3>)-O-) i-R 5>) (I). The units -(-CH 2-CH(R 2>)-O-) kand (-CH 2-CH (R 3>)-O-) lare arranged in the block structure in hydrocarbon (I). k : 10-150; l : 5-25; R 1> : H or CH 3; R 2> : H, CH 3or C 2H 5; R 3> : 2C or ether of formula (-CH 2-OR 9); R 9> : 2C; R 4> : single bond or divalent linkage comprising -(C nH 2 n)-[R 4> 1>], -O-(C nH 2 n)-[R 4> 2>] or -C(O)-O-(C nH 2 n-)-[R 4> 3>]; R 4> 1> : -CH 2- (preferred), -CH 2-CH 2-, -CH 2-CH 2-CH 2-; R 4> 2> : -O-CH 2-CH 2-, -O-CH 2-CH 2-CH 2- or preferably -O-CH 2-CH 2-CH 2-CH 2-; R 4> 3> : -C(O)-O-CH 2-CH 2- (preferred), -C(O)O-CH(CH 3)-CH 2-, -C(O)O-CH 2-CH(CH 3)-, -C(O)O-CH 2-CH 2-CH 2-CH 2- or -C(O)O-CH 2-CH 2-CH 2-CH 2-CH 2-CH 2-; n : 1-6; and R 5> : H or 1-30C hydrocarbon.

    Abstract: The invention relates to mixtures comprising (A) at least one hydraulic or latent hydraulic binding agent, (B) at least one copolymer obtainable by converting (a1) at least one ethylenic unsaturated comonomer having at least one functional group, selected from COOH groups, sulfonic acid groups, nitrile groups, hydroxyalkyl groups, and amino groups, or (a2) at least one (co)polymer of at least one ethylenic unsaturated comonomer having at least one functional group selected from COOH groups, sulfonic acid groups, nitrile groups, hydroxyalkyl groups, and amino groups, having (ß) at least one oligomer or polymer compound obtainable by converting (a) at least one ethylenic unsaturated di- or polycarbolic acid or an anhydride or ester thereof, with (b) at least one at least trifunctional alcohol, and (c) at least one compound of the general formula I wherein the variable are defined as follows: R1 is selected from C1-C4-alkyl and hydrogen, A is identical or different and selected from C2-C6-alkylene, n is in the range of 4 to 40, and (d) optionally at least one further compound having at least one COOH group or at least one alcoholic OH group per molecule.
