| Abstract |
A series of polyesters containing a piperidinium, pyrrolidinium cation backbone are successfully synthesized from dihydroxyl room temperature ionic liquid monomers (RTILs). 1:1 ratio of the cation unit and sebacate is confirmed by 1H NMR. All PF6- and Tf2N- polyesters are amorphous from differential scanning calorimetry (DSC) results. PF6- polyesters with C11 spacers show melting peak at 64 and 65 ℃ (piperidinium and pyrrolidinium, respectively) only during the first heating scan. Glass transition temperatures (Tg) of the PF6- polyesters are shown between -7 and -21℃, however the Tf2N- polyesters do not have Tg above -50 ℃. Highest room temperature ionic conductivity during the ionic polyesters is up to 1.01x10-4 S·cm-1. All Tf2N- polyesters show higher conductivities than the PF6- ones and these results are corresponding to the previous reported ionic liquid-based polyesters. |
