Abstract

<abstract abstract-type="main" id="pi4976-abs-0002"> <title>Abstract</title> <p id="pi4976-para-0002">1‐Butyl‐3‐methylimidazolium hexafluorophosphate (BMIMPF₆) 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 FeCl₃.6H₂O as the catalyst and Fe(0) wire as the reducing agent. The polymers obtained with BMIMPF₆ had controlled molecular weights and low <italic>M</italic>_w/<italic>M</italic>_n values (&lt;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.</p> </abstract>
