)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.

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.

(wherein n is an integer of 1 to 6, a is an integer of 1 to 4, and b is an integer of 1 to 3). The graft copolymer is an oligomer compound having a perfluoroalkyl group containing 6 or less carbon atoms, which is said to have low bioaccumulation potential, and having, when used as an active ingredient of a mold-releasing agent, mold release performance equivalent to that of a compound having a perfluoroalkyl group containing 8 or more carbon atoms.
