Abstract

The widespread use of ionic liquids (ILs) in reversible deactivation radical polymerization (RDRP) procedures has opened new pathways to address the problems caused by hazardous solvents. Additionally, photoinduced RDRP (photoRDRP) of methacrylate monomers in recyclable ILs has been developed, which is catalyzed by magnetic nano zero-valent iron (nZVI), enabling incredible control over M n and Đ s during the polymerization of methyl methacrylate (MMA) by simply turning the UVA radiation (λ max ≈ 352 nm) “ON” and “OFF”. This allows for good temporal control. Furthermore, the chain end fidelity was determined through the synthesis of many distinct diblock copolymers with acceptable Đ s values (≤1.20).
