Zusammenfassung:	It has been discovered by in present invention that, compared with a fluorosurfactant having only one betaine group per molecule, a fluorosurfactant having a plurality of betaine groups per molecule is superior in its ability to undergo electrostatic interaction with other components of a fire fighting composition thereby improving the performance of the fire fighting composition. Previously known fluorosurfactants comprise only one betaine group per molecule. In contrast, the present invention provides for a fluorobetaine copolymer containing a plurality of betaine groups. L'invention a permis de découvrir que, par rapport à un tensioactif fluoré comprenant un seul groupe bétaïne par molécule, un tensioactif fluoré comprenant plusieurs groupes bétaïne par molécule est plus apte à subir une interaction électrostatique avec d'autres composants d'une composition anti-incendie, ce qui permet d'améliorer les performances de ladite composition anti-incendie. Les tensioactifs fluorés connus comprennent uniquement un groupe bétaïne par molécule. Par opposition, l'invention permet d'obtenir un copolymère de bétaïne fluoré contenant plusieurs groupes bétaïne.
