【Abstract】 New lithium poly(polyfluoro alkoxy) sulfonyl imides were prepared and characterized by IR, 1H NMR , as well as 19 F NMR spectrometry. The GPC measurements showed that their average molecular weight was in the range of 1?200～4?900. The corresponding number of polymerization n was about 4～9. The DSC determinations have approved their good thermostability. Furthermore, the electrochemical studies have disclosed their excellent electro conductivity in PC DME(φ=1∶2) and high anodic oxidation potentials in PC.更多还原
