Abstract:
PURPOSE: A water-dispersible emulsion polymerization method of a vinylidene fluoride-containing fluorine based monomer is provided to simplify post-treatment process by using a surfactant hardly accumulated in human body with low toxicity, and to obtain high polymerization rate, and moderate dispersion stability and yield. CONSTITUTION: A polymerization method of a fluorine based monomer comprises a step of polymerizing one or more kinds of fluorine based water-dispersible emulsion monomers by using a fluorosulfonate-based surfactant in chemical formula 1: RfX(CH2)nSO3M. In chemical formula 1, Rf is CF3 or C2F5, X is O, C6H4O, or CF3N, M is metallic ion, and n is an integer from 4-12. The fluorine based monomer is vinylidene fluoride, or a mixture in which one or more kinds selected from the vinylidene fluoride, tetrafluoroethylene, chlorotrifluoroethylene, hexafluoropropylene, and vinyl fluoride are mixed.
