Summary: Novel crosslinked porous particles based on the ionic copolymer of 1,1,3,3‐tetramethylguanidine acrylate (TMGA) and N , N ‐methylenebisacrylamide (MBA) were prepared via an inverse suspension polymerization using cyclohexane as continuous phase and Span 60 as the dispersant. The SO 2 absorption–desorption properties of the P(TMGA‐ co ‐MBA) particles were studied for the first time. The particles showed excellent SO 2 absorption properties: high capacity and rate. These absorption properties, as well as the particle volume, shape, and morphology, remained unchanged during the SO 2 absorption–desorption cycles. The material appeared to be a good candidate as SO 2 absorbent for fuel gas desulfurization (FGD) and purification of other SO 2 ‐containing gases.Optical microscope image of the P(TMGA‐ co ‐MBA) porous particles.
