  • FLUORINATED SURFACTANTS FOR MAKING FLUOROPOLYMERS
    Publication number: 20110034604
    Abstract: 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.
    Type: Application

  • Fluorinated surfactants for use in making a fluoropolymer
    Patent number: 7659333
    Abstract: The present invention provides a fluorinated surfactant having the general formula: [Rf—(O)t—CQH—CF2—O]n—R—G??(I) wherein Rf represents a partially or fully fluorinated aliphatic group optionally interrupted with one or more oxygen atoms, Q is CF3 or F, R is an aliphatic or aromatic hydrocarbon group, G represents a carboxylic or sulphonic acid or salt thereof, t is 0 or 1 and n is 1, 2 or 3. The surfactant is particularly useful in polymerizing fluorinated monomers in an aqueous emulsion polymerization.
