A new poly(ionic liquid) of N , N ‐methylenebisacrylamide (MBA)‐crosslinked‐poly(4‐vinylbenzyltriethylammonium hexafluorophosphate)(MBA‐crosslinked‐P[VBTEA][PF 6 ]) is prepared through the ion exchange of KPF 6 with the precursor of MBA‐crosslinked‐P[VBTEA][Cl]; the precursor is synthesized by 4‐vinylbenzyltriethylammonium chloride and MBA via inverse suspension polymerization. MBA‐crosslinked‐P[VBTEA][PF 6 ] is a thermally stable (decomposes at nearly 300°C) and porous (apparent porosity of 64.3% and specific surface of 39.12 m 2 /g) polymer particle with high purity, as indicated by Fourier transformed infrared, energy dispersive spectroscopy, thermogravimetric, scanning electron microscopy, and porous analyses. It is observed that MBA‐crosslinked‐P[VBTEA][PF 6 ] has good CO 2 adsorption capability of 14.04 mg/g at 0.2 MPa and 25°C, and can be recovered by desorption at vacuum and 80°C, and reused with 99% CO 2 adsorption after four cycles.
