Abstract
A mixture of polyfluoroalkadienes represented by the general formulae: CF(CF)CF═CH(CF)CH═CH[Ia] and CF(CF)CH═CF(CF)CH═CH[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: CF(CF)CH(CF)(CHCH)I [II], with an organic basic compound. The polyfluoroalkadiene mixture is compounds having a perfluoroalkyl group in which the number of successive CFgroups 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.
