Micrometer‐sized poly(ionic liquid) (PIL) particles with an anionic side chain, poly(1‐butyl‐3‐methylimidazolium 3‐sulfopropyl methacrylate) (poly([Bmim][SPMT])), are successfully prepared by dispersion polymerization at 60 °C in ethanol/ethyl acetate (2/8, w/w) with poly(vinylpyrrolidone) as a stabilizer. However, the obtained particles do not maintain the particulate state during drying at room temperature due to poly([Bmim][SPMT])’s low glass‐transition temperature, below room temperature. In order to prevent coalescence and maintain particle shape, a cross‐linking monomer is added after the nucleation stage of dispersion polymerization. Moreover, Fourier‐transform infrared spectroscopy (FT‐IR) demonstrates cation exchange between the obtained particles and metal cations (Ag + ).
