(FR) COMPLEXES POLYELECTROLYTES SERVANT D'AGENTS EPAISSISSANTS POUR SOLUTIONS SALINES A GRANDE FORCE IONIQUE
Abstract: front page image
(EN)A polyelectrolyte complex composition capable of viscosifying or thickening an aqueous high salt-containing system comprises a mixture of at least one anionic polymer and at least one cationic polymer in an inorganic salt-containing aqueous medium. The anionic polymer and cationic polymer can each be linear and water-soluble, crosslinked and water-soluble, or crosslinked and water-insoluble or swellable.
(FR)La présente invention concerne une composition de complexes polyélectrolytes capable de rendre visqueux ou d'épaissir un système aqueux à forte teneur en sel, laquelle composition comprend un mélange d'au moins un polymère anionique et d'au moins un polymère cationique dans un milieu aqueux contenant du sel inorganique. Le polymère anionique et le polymère cationique peuvent chacun être linéaires et solubles dans l'eau, réticulés et solubles dans l'eau, ou réticulés et insolubles dans l'eau ou dilatables.
