Abstract: La presente invención se refiere a un proceso para preparar macromonómeros hidrofóbicamente asociados M y a los nuevos macromonómeros preparados por medio del proceso de acuerdo con la invención. Los macromonómeros M comprenden un grupo copolimerizable etilénicamente insaturado y una estructura de poliéter en forma de bloque, donde el último consiste en un bloque de polietilenoxi y un bloque de polialquilenoxi hidrofóbico que consiste en unidades de alquilenoxi que tiene al menos 4 átomos de carbono. Opcionalmente, los macromonómeros M pueden tener un bloque polietilenoxi terminal. Los macromonómeros preparados por el proceso de acuerdo con la invención son apropiados para reaccionar con otros monómeros, en especial con acrilamida, para dar un copolímero hidrosoluble hidrofóbicamente asociado.

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.

Abstract: The invention relates to a method for oil recovery, according to which an aqueous formulation comprising at least one water-soluble, hydrophobically associating copolymer is forced through at least one injection well in an oil deposit and crude oil is extracted from the oil deposit through at least one production well, said deposit being at a temperature of between 35°C and 120°C, preferably between 40°C and 90°C. The water-soluble, hydrophobically associating copolymer comprises at least acryl amide or derivatives thereof, a monoethylenically unsaturated monomer having anionic groups and a monoethylencally unsaturated monomer that can cause the association of the copolymer.

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.
