    Abstract: PURPOSE:To obtain a polyfluoroalkene in high yield a relatively short time by reacting an allyl halide derivative with a perfluoro-2-pentene in the coexistence of a specific fluoride and an alkali metallic iodide. CONSTITUTION:An allyl halide derivative of formula I (X is halogen; R1 to R3 are H, halogen or 1-20C alkyl) is made to react with a perfluoro-2- methyl-2-pentene to afford the objective polyfluoroalkene of formula II. In the process, at least two fluorides selected from the group of alkali metallic fluorides, alkaline earth metallic fluorides and PbF2 are used in combination (especially preferably a mixture of KF and/or NaF with CsF, BaF2 or PbF2), and alkali metallic iodides (especially preferably KI) are made to coexist. The reaction is carried out in an aprotic polar solvent (especially N,N- dimethylacetamide or N,N-dimethylformamide). The reaction can be carried out even by using an allyl chloride derivative as the raw material. The resultant polyfluoroalkene is useful as a raw material for industrial materials having characteristics such as excellent heat resistance or water and oil repellency.

    Abstract: PURPOSE:To obtain a triboelectrification donating member which gives excellent positive electrification property by incorporating a specified fluorine-contg. quaternary ammonium salt compd. into at least the surface of the member. CONSTITUTION:The triboelectrification donating member contains a fluorine- contg. quaternary ammonium salt compd. in at least the surface thereof. In formula, X is -SO2- or -CO-, R1-R4 are H, lower alkyl groups of 1-10 carbon number or aryl groups, and (n) and (m) are positive integers. This compd. may be dispersed in a solvent or dispersion medium for use, or dispersed in a resin. The resin to be used is, for example, polystyrene, polyacrylate, etc. The coating liquid thus obd. is applied on a base body by dipping, spraying, or brush coating, and dried to obtain the triboelectrification donating member. Or, the resin in which this compd. is dispersed may be molded to obtain the triboelectrification donating member.
