    Abstract: The invention relates to sulfonic acid group-containing copolymers, which also contain the following constituents that are incorporated by polymerization in a statistical or block-by-block manner: (a) 30 to 95 mol % of a least one monoethylenically unsaturated carboxylic acid, one monoethylenically unsaturated carboxylic acid ester, or one water-soluble salt of a monoethylenically unsaturated carboxylic acid; (b) 3 to 35 mol % of at least one sulfonic acid group-containing monomer of formula (I), in which the variables have the following meanings: R represents hydrogen or methyl; X represents a chemical bond or -COO-R1-; R1 represents unbranched or branched C1-C4 alkylene; M represents hydrogen, alkali metal or ammonium, and; (c) 2 to 35 mol % of at least one non-ionic monomer of formula (II), in which the variables have the following meanings: R2 represents hydrogen or methyl; R3 represents a chemical bond or unbranched or branched C1-C6 alkylene; R4 represents identical or different unbranched or branched C2-C4 alkylene groups; R5 represents unbranched or branched C1-C6 alkyl, C5-C8 cycloalkyl or aryl, and; n represents 3 to 50. These copolymers are used as an additive in detergents and cleansers.

    IPC: E21B43/22

    Abstract: The method involves introducing the polymer into oil stores. The water-soluble polymer is used in the form of a dispersion of the water-soluble polymer as well as at least one water-soluble polymer stabilizer. The viscosity of the dispersion in the neutral and basic pH region is higher than in the acidic region.
