Abstract

Polymerized ionic liquids (PILs) were successfully prepared by using 4-(vinylbenzyltrimethyl)ammonium, [VBTMA] as the cation and alanine as the anion. The monomer [VBTMA]Ala was reacted with AIBN as radical initiator to produce poly[VBTMA]Ala. The polymer was characterized by using NMR and FTIR. Thermal degradation behavior for Poly[VBTMA]Ala was 168.70 °C and glass transition temperature (Tg) was not detected even at second cycle. The surface area, pore size and pore volume were determined by using BET surface area and pore size analyzer which showed that Poly[VBTMA]Ala has mesoporous structure. The morphology was determined by FESEM. The CO2 adsorption was measured by gas adsorption cell which showed that the mole of CO2 adsorb increased as pressure increased.
