Abstract
A polyfluoro-1-alkene represented by the general formula: CF(CF)CH(CF)CH═CH[I], wherein n is an integer of 0 to 5, and m is an integer of 1 to 7, is produced by reacting a polyfluoroalkyl iodide represented by the general formula: CF(CF)CH(CF)(CHCH)I [II], wherein n is an integer of 0 to 5, and m is an integer of 1 to 7, with an inorganic basic compound in the presence of a phase transfer catalyst. 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.
