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.

A mixture of polyfluoroalkadienes represented by the general formulae: CF3(CF2)nCF═CH(CF2)m+1CH═CH2 [Ia] and CF3(CF2)n+1CH═CF(CF2)mCH═CH2 [Ib], wherein n is an integer of 0 to 5, and m is an integer of 0 to 6, is obtained as a mixture fraction of products [Ia] and [Ib] by reacting a polyfluoroalkyl iodide represented by the general formula: CF3(CF2)n+1CH2(CF2)m+1(CH2CH2)I [II], with an organic basic compound. The polyfluoroalkadiene mixture is compounds having a perfluoroalkyl group in which the number of successive CF2 groups is 5 or less, and is effectively used as a copolymerizable monomer in the production of resinous or elastomeric fluorine-containing copolymers, which are used as active ingredients of surface-treating agents, such as water- and oil-repellents and mold-release agents.

to a dehydrofluorination reaction in the presence of a nitrogen-containing heterocyclic compound catalyst, and has a lower critical micelle concentration and less surface tension at that time, therefore, the mixture of polyfluoroalkene carboxylic acids or salts thereof can be effectively used as a surfactant in the polymerization of fluorine-containing monomers.
