• ; ionic liquid; polymeric ionic liquid; RAFT polymerization; Introduction Ionic liquids (ILs) are organic salts. Most of them have a melting point below 100 °C [1][2]. These organic salts do not have the same structure like inorganic salts. This is due to the structure of the ion pairs. They are built of

• the quarternized AP oligomer may be applied as a polymeric ionic liquid or a precursor of polymeric ionic liquids. In this study, we investigate quarternization of an AP oligomer with methyl iodide to obtain a soluble oligomer (Scheme 1b) and characterize the quarternized oligomer in dilute solutions

• . The conformation of oligoAPMe was further discussed based on the touched bead model. Since the oligoAPMe obtained in this study was solid and the iodide counterions were not significantly dissociated in DMSO, it is difficult to apply the oligoAPMe as a polymeric ionic liquid. However, if appropriate
