AMPHIPHILIC MACROMONOMERS, METHOD FOR PRODUCING AMPHIPHILIC MACROMONOMERS, COPOLYMERS COMPRISING AMPHIPHILIC MACROMONOMERS AND THE USE OF SUCH COPOLYMERS FOR TERTIARY PETROLEUM PRODUCTION

摘要

The invention relates to a method for tertiary petroleum production using water-soluble hydrophobically associating copolymers which comprise acrylamide or acrylamide derivatives and amphiphilic macromonomers based on acrylamide and/or maleic acid imides or amides and/or itaconic acid imides or amides. The invention also relates to water-soluble hydrophobically associating copolymers and macromonomers of the aforementioned types, and to the production thereof.
