    Abstract: The invention relates to the use of a mixture containing a surfactant and a cosurfactant in the form of an aqueous solution for flooding underground hydrocarbon fields in order to mobilise and extract hydrocarbons therefrom, wherein the cosurfactant is embodied in the form of a substance or the group of substances selected from an amphiphilic comb polymer comprising a backbone which is provided with two or more side chains which differ from each other and/or from the backbone in terms of the amphiphilic character thereof, the amphiphilic polymer comprises one or several hydrophobic sub-groups [A2] based on a polyisobutene block, wherein at least 50 Mol % of polyisobutene macromolecules have terminal double bonds and one or several hydrophobic sub-groups [A2] or an amphiphilic polymer of a general structural formula (I).

    Abstract: Water-soluble copolymers which comprise, in copolymerized form, (a) 60 to 99% by weight of at least one monoethylenically unsaturated polyalkylene oxide monomer of the formula I (see formula I) in which the variables have the following meanings: X is -CH2- or -C(O)-, if Y is -O-; is -C(O)-, if Y is -NH-; is -O- or -O-(CH2)4-, if Y is a chemical bond; Y is -O-, -NH- or a chemical bond; R1 is hydrogen or methyl; R2 is C2-C4-alkylene radicals, which may be identical or different and also linear or branched, but where at least 50% of the radicals R2 are ethylene; R3 is C1-C22-alkyl, phenyl, p-(C1-C12-alkyl)phenyl or hydrogen; n is an integer from 6 to 50, (b) 1 to 40% by weight of at least one nonquaternized dipolar monomer comprising at least one nitrogen atom, (c) 0 to 39% by weight of other nonionic monoethylenically unsaturated monomers and (d) 0 to 10% by weight of other anionic monoethylenically unsaturated monomers and have an average molecular weight M w of from 2000 to 500 000 D, and the use of the copolymers as dispersants and sequestrants for pigmented materials, as additive for detergents, laundry pretreatment compositions, cleaners for hard surfaces, dentifrices and bodycare compositions, and as auxiliaries for textile processes, paper making and paper processing and deinking processes.
