Polymerization‐induced self‐assembly of 2‐hydroxypropyl methacrylate is conducted in water and water/MeOH using a CO₂‐responsive macroRAFT agent in the form of a statistical copolymer comprising N,N‐diethylaminoethyl methacrylate (DEAEMA) and poly(ethylene glycol) methyl ether methacrylate (M _n = 475 g mol⁻¹). Pressurization with CO₂ leads to protonation of DEAEMA units within the stabilizer block, thereby offering a means of adjusting the charge density of the coronal layer. It is demonstrated that a wide range of tunable particle morphologies are accessible by simply varying the CO₂ pressure during polymerization in the range of 10–45 bar.

在压缩CO2下聚合诱导的自组装：使用对CO2敏感的MacroRAFT剂控制形态

聚合诱导的甲基丙烯酸2-羟丙酯的自组装反应是在水和水/甲醇中，使用CO ₂响应的macroRAFT试剂，以统计共聚物的形式，由甲基丙烯酸N，N-二乙基氨基乙基酯（DEAEMA）和聚乙二醇制成。甲基丙烯酸甲酯甲基醚（M _n  = 475 g mol ^-1）。用CO ₂加压导致稳定剂块内的DEAEMA单元质子化，从而提供了一种调节冠状层电荷密度的方法。结果表明，只需在10-45 bar的范围内改变聚合过程中的CO ₂压力，即可获得各种可调的颗粒形态。
