The invention provides a fluorinated surfactant having the general formula:
[Rf—(O)t—CHF—(CF2)n—COO—]iXi+ (I) , wherein Rf represents a partially or fully fluorinated aliphatic group optionally interrupted with one or more oxygen atoms, t is 0 or 1 and n is 0 or 1; Xi+ represents a cation having a valence i, and i is 1, 2 or 3. The surfactant can be used in emulsion polymerization of fluoromonomers to prepare fluoropolymers. Fluoropolymers, i.e. polymers having a fluorinated backbone, have been long-known and used in a variety of applications due to their several desirable properties such as heat resistance, chemical resistance, weatherability, UV-stability, etc.
