A composition is disclosed that includes fluorinated polymer and a non-fluorinated polymer. The fluorinated polymer includes first divalent units independently represented by formula and second divalent unit independently comprising a pendent cationic, anionic, amphoteric, or amine-oxide group or a pendent poly(alkyleneoxy) segment. The non-fluorinated polymer is R2O-(EO)p-(R3O)q-(EO)p-R2 or R2O-(R3O)q-(EO)p-(R3O)q-R2. A method of making the composition and methods of reducing the surface tension of a liquid and a method of treating a hydrocarbon-bearing formation are also disclosed. L'invention concerne une composition qui comprend un polymère fluoré et un polymère non fluoré. Le polymère fluoré comprend des premières unités divalentes représentées indépendamment par la formule et une seconde unité divalente comprenant indépendamment un groupe latéral cationique, anionique, amphotère ou amine-oxyde ou un segment latéral poly(alkylèneoxy). Le polymère non fluoré est R2O-(EO)p-(R3O)q-(EO)p-R2 ou R2O-(R3O)q-(EO)p-(R3O)q-R2. L'invention concerne également un procédé de fabrication de la composition et des procédés de réduction de la tension de surface d'un liquide et un procédé de traitement d'une formation pétrolifère.
