Beschreibung
Zusammenfassung:	The present invention refers to the use of anionic water-soluble polymers being partially or totally neutralized with an organic counter-ion for oil filed application, especially tertiary oil recovery steps. La présente invention concerne l'utilisation de polymères hydrosolubles anioniques, partiellement ou totalement neutralisés par un contre-ion organique, cela étant applicable dans les champs pétrolifères et, en particulier, lors des étapes de collecte des hydrocarbures de type tertiaire.
