-
A partially-fluorinated surfactant having internal methylene groups and having the formula Rf --(CH2)m --R'f --COOM wherein m is 1-3, Rf is perfluoroalkyl or perfluoroalkoxy, containing 3-8 carbon atoms, R'f is linear or branched perfluoroalkylene containing 1-4 carbon atoms, and M is NH4, Li, Na, K, or H is useful in polymerization of fluorinated monomers. High molecular weight can be achieved in homopolymerization of tetrafluoroethylene.
