Abstract: The present invention relates to the preparation of polymers that are of use in particular as a rheology agent, and are suitable for use in very concentrated saline media, which comprises a step of micellar radical polymerization in which are brought into contact, in an aqueous medium: —hydrophilic monomers; —hydrophobic monomers in the form of a micellar solution, containing micelles comprising these hydrophobic monomers; —a radical polymerization initiator; and —preferably an agent for controlling radical polymerization, wherein said micelles comprise at least one surfactant of amphoteric nature. The polymers obtained according to the invention are in particular of use for enhanced oil recovery.

Abstract: An aqueous formulation for enhanced oil recovery may include at least one surfactant and at least one associative polymer. The associative polymer may be obtained by micellar radical polymerization by bringing into contact, in an aqueous medium, hydrophilic monomer dissolved in the aqueous medium, hydrophobic monomers in the form of a micellar solution, at least one radical polymerization initiator, and preferably at least one radical polymerization control agent.
