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⁺).

分散聚合制备阴离子侧链聚离子液体颗粒。

通过分散聚合成功地制备了具有阴离子侧链的微米级聚（离子液体）（PIL）颗粒，聚（1-丁基-3-甲基咪唑鎓3-甲基磺丙基甲基丙烯酸）（poly（[Bmim] [SPMT]））在60°C的乙醇/乙酸乙酯（2/8，w / w）中，以聚乙烯吡咯烷酮为稳定剂。但是，由于聚（[Bmim] [SPMT]）的室温以下较低的玻璃化转变温度，因此在室温下干燥过程中获得的颗粒无法保持颗粒状态。为了防止聚结并保持颗粒形状，在分散聚合的成核阶段之后添加交联单体。此外，傅立叶变换红外光谱（FT-IR）证明了所得颗粒与金属阳离子（Ag ⁺）之间的阳离子交换。
