反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Solvency tests with 50% by volume 4-bromo-3-chloro-3,4,4-trifluorobutene and 50% by volume ethyl nonafluorobutyl ether were performed. The solvency characteristics of these mixtures matched or exceeded that of CFC-113 with Krytox and Jet Lube. The solvency of the individual components was inferior to that of CFC-113 toward Krytox and Jet Lube, illustrating the effectiveness of using mixtures as taught by this invention. Similarly, mixtures of 4-bromo-3,3,4,4-trifluorobutene and methyl nonafluorobutyl ether produced solvency characteristic that met or exceeded those of CFC-113.

实验步骤: A supply of BCTFB was obtained by reacting ethylene with dibrominated CTFE in 1,1,1,3,3-pentafluorobutane at 120° C. for 4 hours using a mixture of tert-butyl peroxypivalate (TBPPi, 3 mol %) and 2,5-bis(tert-butylperoxy)-2,5-dimethylhexane (Trigonox 101, 4.5 mol %) as radical initiators, with the resulting structure being Br—CF2—CFCl—CH2—CH2—Br after distillation under vacuum. This was dehydrochlorinated with KOH in refluxing methanol for 15 hours, forming Br—CF2—CFCl—CH═CH2 (BCTFB). Successful radical copolymerization of CTFE (96 mol % in the feed) with BCTFB initiated by TBPPi (2 mol % with respect to both monomers) was carried out at 74° C. in a 100 mL autoclave. The 19F NMR spectrum of the obtained polymer is shown in FIG. 7. A supply of BCTFB was obtained at 120° C. for 4 hours after distillation under vacuum in refluxing methanol for 15 hours
