Synthesis and thermal properties of organic ionic plastic crystals polymers |
| 초록 |
New ionic polymers containing dicationic cyclic ammonium cations are synthesized and characterized. The acrylate monomers of C2-bridged bis-imidazolium with different alkyl groups are prepared as polymerizable organic ionic plastic crystals. Thermal stability order of the OH functional OIPCs exhibits BF4->PF6->I->Cl-. The bis-imidazolium PF6- salt with n-hexyl and 6-hydroxyhexyl groups shows multiple solid-solid phase transitions before melting temperature. Most of the bis-imidazolium salts with n-undecyl and 11-hydroxyundecyl also show multiple phase transitions and iodide salt shows the lowest entropy of fusion 14J/K·mol. Free radical polymerization with an initiator azobisisobutyronitrile(AIBN) is used to prepare the ionic polymers. The ionic polymers from bis-imidazolium salts with undecyl groups show multiple transitions below Tm except for polymer with chloride salt. Different crystaline morphologies by the phase transitions are found below the polymer's Tm from the POM images. |
