제목 Synthesis and Characterization of Polyurethane Ionomers Based On Pyrrolidinium Ionic Liquid Monomers
초록 Novel polyurethane ionomers containing pyrrolidinium cations on the polymer backbone is synthesized from a dihydroxyl functionalized pyrrolidinium ionic liquid monomer and 4,4’-diphenylmethane diisocyanate (MDI). Polyurethane copolymers are also synthesized with comonomers such as polyethylene glycol(PEG) or Jeffamine® ED-900. FT-IR and 1H NMR are used to see the polymerization reaction completion and mole ratio of the ionic and non-ionic monomers in the polyurethane ionomers. The thermal properties of the all polyurethane ionomers are investigated by differential scanning calorimetry and thermal gravimetric analysis. The polyurethane ionomers with PEG4000 contain crystalline phases at room temperature, however the other polyurethane ionomers are amorphous throughout the whole measuring temperature range. The polyurethane ionomers with PEG1000 and Tf2N- anions shows ionic conductivity 1.77 x 10-2 S/cm at 120 oC.
