Reverse atom transfer radical polymerization of methyl acrylate in the presence of a conventional radical initiator (2,2′‐azoisobutyronitrile, AIBN) in bulk was successfully implemented via a new polymerization procedure. The system first reacts at 65–70°C for ten hours, then polymerizes at 100°C. Various mole ratios of AIBN to Cu II Cl 2 were used in this work, all of which result in a well‐controlled radical polymerization with high initiation efficiency and narrow molecular weight distribution, i.e., the polydispersity is as low as M̄ w / M̄ n = 1.36.
