| Abstract: | A series of new long-side chain polyether ionic liquids have been prepared starting from N-methylimidazole and polyepichlorohydrin （PECH ）. The influence of reaction time, reaction temperature and reactant mixture ratio on the grafting ratio of PECH is investigated. These compounds have been characterized by infrared spectroscopy and element analysis. The optimal process conditions are as follows ： the reaction time is 6h, the reaction temperature 70℃ ; n （ PECH ） ： n （ ionic liquid ）= 1 ： 1.5. |
