Title (EN) ETHYLENE-TETRAFLUOROETHYLENE CARBOXYLIC ACIDS AND SALTS
(FR) ACIDES ÉTHYLÈNE-TÉTRAFLUOROÉTHYLÈNE CARBOXYLIQUES ET SELS CORRESPONDANTS
Abstract:
(EN) Polyfluorinated carboxylic acids and their salts containing an ethylene-tetrafluoroethylene moiety, which are useful as surfactants in a process for the dispersion polymerization of fluorinated monomer in an aqueous polymerization medium.
(FR) L'invention porte sur des acides carboxyliques polyfluorés et leurs sels contenant une fraction éthylène-tétrafluoroéthylène, qui sont utiles en tant qu'agents tensio-actifs dans un procédé de polymérisation en dispersion d'un monomère fluoré dans un milieu de polymérisation aqueux.
