Polymeric ionic liqs. have shown great potential in numerous application fields, and an easy access to polymerizable monomer is the key to the polymd. ionic liqs. The polymerizable monomer is usually synthesized via the quaternization of a corresponding bromide, which is usually prepd. from bromination of the corresponding alc. but with a low yield. In this study, a polymerizable monomer was prepd. by quaternization of a mesylate, derived from the corresponding alc., followed by an ion exchange reaction. The polymerizable ILs M1-M4 showed ionic cond. as high as 10-3 S cm-1, and the oxygen effect was obsd. with the lithium salt. Polymeric ionic liqs. P1 and P2 were prepd. via radical polymn. on M1 and M2, and the ionic cond. of polymeric ionic liq. P2 was as high as 2.2 × 10-4 S cm-1 with electrochem. stability exceeding 7 V (vs. Li/Li+).
