以聚甲基丙烯酸甲酯（PMMA）、聚甲基丙烯酸乙酯（PEMA）和聚甲基丙烯酸叔丁酯（PtBMA）为种子粒子，在甲醇/水混合溶剂中进行了离子液体单体[2-（甲基丙烯酰氧基）乙基]三甲基铵双（三氟甲磺酰基）酰胺（[MTMA][TFSA]）的种子分散聚合。对于PMMA和PEMA种子粒子，获得了与聚（离子液体）（PIL）的复合粒子。相比之下，对于PtBMA种子颗粒，形成二次成核的PIL颗粒，并且没有获得PtBMA/PIL复合颗粒。这些结果也预测的理论考虑的基础上计算的界面张力的扩展系数。此外，我们表明，从TFSA到Br和FeCl 4阴离子的PIL/交联PMMA核-壳复合颗粒中的PIL-核的阴离子交换可用于仅改性复合颗粒的核组分的性质。
Seeded dispersion polymerization of an ionic liquid monomer ([2-(methacryloyloxy)ethyl]trimethylammonium bis(trifluoromethanesulfonyl)amide) ([MTMA][TFSA]) was carried out in the presence of poly(methylmethacrylate) (PMMA), poly(ethyl methacrylate) (PEMA), and poly(t-butyl methacrylate) (PtBMA) as seed particles in a methanol/water mixture. For PMMA and PEMA seed particles, composite particles with poly(ionic liquid) (PIL) were obtained. In contrast, for PtBMA seed particles, secondary nucleated PIL particles were formed and no PtBMA/PIL composite particles were obtained. These results were also predicted by theoretical consideration based on the spreading coefficients calculated from the interfacial tensions. Moreover, we showed that anion exchange of the PIL-core in the PIL/cross-liked PMMA core–shell composite particles from TFSA to Br and FeCl4 anions can be used to modify the properties of only the core component of the composite particles.
