## Abstract The reverse atom transfer radical polymerization of methyl methacrylate was investigated in different solvents: xylene, __N,N__‐dimethylformamide, and pyridine. The polymerizations were uncontrolled, using 2,2′‐bipyridine as a ligand in xylene and pyridine because the catalyst (CuBr~2~/
Reverse atom transfer radical polymerization (ATRP) of methyl methacrylate (MMA) employing 2,2-azobisisobutyronitrile (AIBN)/CuCl 2 /bipyridine(bipy) as the initiating system was approached at 80 8C in two ionic liquids, 1-butyl-3-methylimidazolium tetrafluoroborate ([C 4 mim][BF 4 ]) and 1-dodecyl-
