Abstract : Perfluorohexadiene was prepared by coupling 3-iodopentafluoropropene-1. Telomerization reactions were developed, which resulted in the preparation of precursors for perfluorohexadiene-1,5, perfluoroheptadiene-1,6, and perfluorooctadiene-1,7 from iodine monochloride, chlorotrifluoroethylene, and tetrafluoroethylene. Perfluorooctadiene, prepared from its precursor, polymerized readily under high pressure, and several polymer samples were obtained. These samples showed a high degree of cyclization as shown by infrared studies. (Author)
