| Popis: | Three ionic monomers based on a 1-vinylimidazolium cation, 1-vinyl-3-methylimidazolium methyl sulfate, 1-vinyl-3-ethylimidazolium ethyl sulfate, and 1-vinyl-3-propylimidazolium propyl sulfate are synthesized and characterized by thermal and spectroscopic methods. The ionic-liquid monomers (ILMs) are prepared using a halide-free route under ambient conditions by the quaternization reaction of 1-vinylimidazoles with alkyl sulfates. Through freeradical polymerization and rheology analysis, solid freestanding linear polymeric-ionic-liquid (PILs) fi lms are obtained with a tan δ value as low as 0.180. After polymerization, thermal methods show the linear PILs to possess a thermal stability of up to 340 °C, while rheology analysis reveals the fi lms to have a storage moduli value as high as 4.64 × 10 6 Pa. |
