A facilitate and halide-free process to prepare ionic liquid monomers with various anions was developed with dialkylsulphate as the alkylating agent. The results imply that the process was efficient to prepare ionic liquid monomers for poly ionic liquids which have been proposed as promising alternative polymer electrolyte for various electric devices such as fuel cell, Li ion battery. Furthermore, ionic conductivity of both the ionic liquid monomers was measured as a function of temperature. Electrochemical window was measured with acyclic voltammogram (CV) method. The results show that it is a facilitate and versatile method to prepare imidazolium type ionic liquid monomers without halide impurity.
