Title
(EN) AUTO-INVERTIBLE INVERSE POLYMER EMULSION
(FR) EMULSION INVERSE POLYMERIQUE AUTO INVERSIBLE
Abstract
(EN)
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 hydrosoluble 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.
(FR)
L'invention concerne une émulsion inverse de polymère ayant la particularité de s'auto-inverser sans nécessiter l'utilisation d'un agent inverseur, et contenant un polymère d'au moins un monomère hydrosoluble et d'au moins un macromonomère à LCST. L'invention concerne également l'utilisation de l'émulsion inverse dans les domaines de l'industrie du pétrole et du gaz, du traitement de l'eau, le traitement des boues, de la fabrication du papier, de la construction, de l'industrie minière, des cosmétiques, du textile, de la détergence, ou de l'agriculture.
