1‐Butyl‐3‐methylimidazolium hexafluorophosphate ( BMIMPF 6 ) as a typical ionic liquid (IL) effectively acted as ligand for the control of iron‐mediated activators generated by electron transfer for atom‐transfer radical polymerization of methyl methacrylate ( MMA ) in the presence of a limited amount of oxygen, using FeCl 3 . 6H 2 O as the catalyst and Fe(0) wire as the reducing agent. The polymers obtained with BMIMPF 6 had controlled molecular weights and low M w / M n values (<1.40). Moreover, a well‐defined final product PMMA without additional processing was easily obtained and the reducing agent (iron wire) could be recycled and reused effectively just by washing three times with solvents.
