    摘要： The present invention provides a method of producing a fluoroelastomer excellent in dispersion stability at low cost, at a high rate of polymerization and in high yields. The present invention is a method of producing a fluoroelastomer comprising an emulsion polymerization of a fluorinated monomer in the presence of a water-soluble radical polymerization initiator, wherein the emulsion polymerization is carried out in the presence of a compound (1) containing a functional group reactive in radical polymerization and a hydrophilic group and a fluorinated compound (2) containing a fluorocarbon group comprising 1 to 6 continuously united carbon atom with fluorine atom directly bound to each of them as well as a hydrophilic group.
