| Abstract |
Novel polyurethane ionomers are synthesized using hydroxyl pyrrolidinium ionic liquid monomers. Ionic polyurethanes with different diisocyanates, such as [Methylenedipheny 4,4‘-diisocyanate](MDI), [Tolylene-2,4-diisocyanate](TDI) and [Dicyclohexylmethane 4,4-disocyanate](HMDI) are investigated about their chemical and physical properties by different spacers. Also, different anions, such as Br-, Tf2N-, and PF6- are used for the ionic polyurethanes and they are characterized to see the different properties. The pyrrolidinium bromide-based polyurethanes with TDI spacers has the lowest glass transition temperature (Tg), 37 °C on its different scanning calorimetry thermogram. From thermal gravimetry experiments, the Tf2N- polyurethanes show a higher thermal stability and lower Tg. |
