Alternatively, the polyfluoro-1-alkene is produced by reacting the polyfluoroalkyl iodide [II] with a nitrogen-containing organic basic compound, and is obtained product [I] as one fraction thereof. By the copolymerization of the polyfluoro-1-alkene with other fluorinated olefin monomers, a fluorine-containing copolymer having excellent light transmittance in the visible light range is formed.
