碩士 === 國立臺北科技大學 === 有機高分子研究所 === 94 === Two monomers FSO2(CF2)4SO2F and FSO2(CF2)6SO2F are synthesized according to Burton’s method. This research studies the condensation polymerization of these two monomers with potassium bis(trimethylsilyl)amide in toluene. The resulting polymers undergo the ion exchange, and then the acidified products react with Li2CO3 to prepare two new types of fluorinated polymeric Li salts- LiPBSI (lithium polyperfluorobutane-1,4-bis-sulfonylimide)andLiPHSI(lithiumpolyperfluorohexane-1,6-bis-sulfonylimide ). The 1H and 19F、13C NMR, GC/MS, FT-IR, TGA ,DSC etc. are used to characterize the new compounds. and their conductivities were measured on the films made from polymeric Li salts and PEO in varying ratios.finally,measured the transference number of Li / LiPBSI PEO / Li cell and Li / LiPHSI PEO / Li cell.
