    Abstract: Water-soluble, hydrophobically associated copolymer (I) comprising (a) at least one monoethylenically unsaturated, water-soluble surface active monomer, and (b) at least one monoethylenically unsaturated hydrophilic monomer (b) different from the monomer (a), is claimed, where during the preparation of (I), additionally (c) a non-polymerizable surfactant is used before the initiation of the polymerization reaction. An independent claim is included for a process for preparing (I) comprising subjecting (a) and (b) to an aqueous solution polymerization in the presence of (c).

    Abstract: Compositions comprising: (A) at least one surfactant of the general formula (I) (R1—[(O—(CH2)2)x1(O—CH(CH3)CH2)x2]O)kP(═O)(OH)3-k  (I) wherein the sequence of the alkyleneoxy units is arbitrary, each R1 independently represents a moiety selected from the group consisting of linear and branched C12-C22-alkyl, C12-C22-alkenyl, C12-C22-alkynyl, (C11-C21-alkyl)carbonyl, (C11-C21-alkenyl)carbonyl and (C11-C21-alkynyl)carbonyl, k represents 1 or 2 and x1 and x2 each independently represent an integer of 0 to 20, the sum of x1 and x2 being a number of 1 to 20; and (B) at least one thickener comprising at least two hydrophobic groups R2 which are linked to one another via a bridging hydrophilic group (α), wherein each R2, independently represents a moiety selected from the group consisting of C8-C32-alkyl, C8-C32-alkenyl, C8-C32-alkynyl, cycloalkyl, aryl, and aryl-C1-C32-alkyl, which in each case may have up to 3 hydroxyl substituents; wherein the composition has a pH which is viscosity-dependent.

    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. Provided that 50% of R 2>is H.
