    Abstract: The present invention relates to a particulate, linear, sheet-like or three-dimensional structure comprising, at least on its surface, a hydrophilicizing amount of at least one acylated polyamine, where at least some of the polyamine nitrogen atoms bear acyl radicals of the formula I R 1 -CO- (I) where R 1 is hydrogen, C 1 -C 27 -alkyl, C 7 -C 27 -alkenyl or C 6 -C 10 -aryl, and where the alkyl, alkenyl and aryl groups may bear at least one substituent selected from the class consisting of hydroxyl, alkoxy, alkoxycarbonyl and NE 1 E 2 , where E 1 and E 2 may be identical or different and are hydrogen, alkyl or acyl, to the use of acylated polyamines for modifying the surface properties of solids, and also to a process for modifying the surface properties of particulate, linear, sheet-like, or three-dimensional structures.

    Abstract: Use of a mixture comprising a surfactant and a cosurfactant in the form of an aqueous solution for flooding underground deposits of hydrocarbons for mobilizing and recovering the hydrocarbons from the underground deposits, the cosurfactant being a substance or a group of substances selected from the following list: an amphiphilic comb polymer having a backbone with two or more side chains attached to the backbone, the side chains differing from one another and/or the side chains differing from the backbone in their amphiphilic character, an amphiphilic polymer having one or more hydrophobic subunits [A2] based on a polyisobutene block, at least 50 mol % of whose polyisobutene macromolecules have terminally arranged double bonds, and one or more hydrophilic subunits [B2], or an amphiphilic polymer having the general structural formula
