Abstract: The invention relates to a method for extracting crude oil by means of CO2-flooding, in which a liquid or supercritical CO2 and at least one alk(en)yl polyglucoside is injected through at least one injection bore into an oil reservoir and crude oil is extracted from the oil reservoir by means of at least one production bore. The alk(en)yl polyglucoside is preferably dissolved in the CO2phase. The invention also relates to a method for extracting crude oil by means of CO2-flooding in which mixtures of alk(en)yl polyglucosides are used with alk(en)yl polyalkoxylates anionic surfactants.

Abstract: The present invention relates to water-soluble, hydrophobically associating copolymers, which are obtained in the presence of a non-polymerisable, surface-active compound and which contain novel hydrophobically associating monomers. The monomers comprise an ethylenically unsaturated group and a polyether block, the polyether block containing a hydrophilic polyethyleneoxy block and a hydrophobic polyalkyleneoxy block, which consists of alkyleneoxy units having at least 4 carbon atoms. The monomers can optionally have a terminal polyethyleneoxy block. The invention further relates to a method for producing the copolymers and to the use thereof.

Abstract: The present invention relates to a process for the preparation of hydrophobically associating macromonomers M and to the novel macromonomers produced by the inventive method. The macromonomers M comprise a copolymerizable, ethylenically unsaturated group and a polyether structure in block form which comprises a polyethylenoxy block and a hydrophobic polyalkylenoxy block consisting of alkylenoxy-units with at least 4 carbon atoms. Optionally, the macromonomers M may comprise a terminal polyethylenoxy block. The macromonomers produced by the inventive method are suitable for reaction with other monomers, in particular with acrylamide, to form a water-soluble, hydrophobically associating copolymer.
