A new controlled/living heterogeneous polymerization technique using RAFT in benign supercritical CO 2 is described involving the formation of monomer‐swollen seed particles by precipitation of macroRAFT agent prior to polymerization. Controlled/living character of the induced precipitation is compared with the equivalent solution polymerization. The large scale synthesis of poly(2‐ethoxyethyl methacrylate)‐ b ‐poly(acrylamides) useful for biomedical applications is made possible with the polymer isolated as powders at high conversions, thus circumventing the requirement for volatile organic solvents. © 2015 Wiley Periodicals, Inc.
