Abstract: La presente invención se refiere a copolímeros hidrosolubles hidrofóbicamente asociados que se obtienen en presencia de un compuesto tensioactivo no polimerizable y que comprenden nuevos monómeros hidrofóbicamente asociados. Los monómeros comprenden un grupo etilénicamente insaturado y un bloque de poliéter, donde el bloque de poliéter comprende un bloque de polietilenoxi hidrofílico y un bloque de polialquilenoxi hidrofóbico que consiste en unidades de alquilenoxi que tiene al menos 4 átomos de carbono. Los monómeros pueden tener opcionalmente un bloque polietilenoxi terminal. La invención también se refiere a procesos para preparar los copolímeros y a su uso.

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.

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.
