Polymerization‐induced self‐assembly of 2‐hydroxypropyl methacrylate is conducted in water and water/MeOH using a CO 2 ‐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 CO 2 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 CO 2 pressure during polymerization in the range of 10–45 bar.
