The present invention relates to a method for preparing a polymer reverse emulsion polymerization comprising the following steps:

Method for synthesising polymers by controlled-radical inverse emulsion polymerisation

The invention relates to an inverse polymer emulsion having the particular feature of auto-inverting without any need for the use of an inverting agent and containing a polymer of at least one water-soluble monomer and at least one LCST macromonomer. The invention also relates to the use of the inverse emulsion in the fields of the oil and gas industry, water treatment, slurry treatment, paper manufacturing, construction, mining, cosmetics, textiles, detergents or agriculture.

Auto-invertible inverse polymer emulsion

This invention relates to a process of enhanced oil recovery by sweeping an underground formation comprising injecting into the underground formation an injection fluid comprising at least one water-soluble LCST macromonomeric polymer.

Method for enhanced oil recovery by means of injection of an aqueous polymer composition having monomeric units from an LCST

A method for diverting an underground formation comprises injecting, into the underground formation, an aqueous solution containing at least one heat-sensitive copolymer of a) at least one water-soluble monomer having at least one unsaturated function capable of being polymerized to form a water-soluble backbone, and b) at least one macromonomer of formula (I)
