Isotactic polymethyl methacrylate (PMMA) was obtained via anionic polymerization of methyl methacrylate (MMA) with ionic liquid (IL) as the solvent. IL acts as both the solvent and an additive in this process, and its interaction with MMA, key to controlling the stereoregularity of the polymer product. The apparent steric hindrance of MMA increases when its carbonyl and vinyl groups interact with IL via electrostatic interactions, resulting in PMMA with well‐controlled stereoregularity. Nobuyuki Otozawa and colleagues provide details of this approach in their article on page 1960. (DOI: 10.1002/pol.20200244)

等规聚甲基丙烯酸甲酯(PMMA)是通过甲基丙烯酸甲酯(MMA)与离子液体(IL)为溶剂的阴离子聚合而制得的。IL在此过程中既充当溶剂又充当添加剂,并且与MMA相互作用,这是控制聚合物产物的立构规整度的关键。当MMA的羰基和乙烯基通过静电相互作用与IL相互作用时,MMA的明显空间位阻增加,导致PMMA的立体规则性得到很好的控制。音泽信行及其同事在其第1960页的文章中提供了这种方法的详细信息。(DOI:10.1002 / pol.20200244)
