A novel Janus compound containing azo‐based thermal initiator and bromo‐based atom transfer radical polymerization (ATRP) initiator group is synthesized. Such compound can be applied in the living radical polymerization of alkyl methacrylate monomers, such as methyl methacrylate, tert ‐butyl methacrylate, and 2‐( N , N ‐dimethylamino) ethyl methacrylate. Polymers with controlled molecular weights and narrow molecular weight distributions are obtained. The structure of polymers is identified by 1 H NMR spectroscopy and matrix‐assisted laser desorption ionization time‐of‐flight mass spectrum. A modified initiator for continuous activator regeneration ATRP mechanism is proposed according to the polymerization behavior, hydrolysis of chain backbone, and end group identification.
