The atom‐transfer radical polymerization (ATRP) of methyl methacrylate (MMA), using α,α′‐dichloroxylene as initiator and CuCl/ N,N,N′,N″,N″ ‐pentamethyldiethylenetriamine as catalyst was successfully carried out under microwave irradiation (MI). The polymerization of MMA under MI showed linear first‐order rate plots, a linear increase of the number‐average molecular weight with conversion, and low polydispersities, which indicated that the ATRP of MMA was controlled. Using the same experimental conditions, the apparent rate constant ( k p app ) under MI ( k p app= 7.6 × 10 −4 s −1 ) was higher than that under conventional heating ( k p app= 5.3 × 10 −5 s −1 ). © 2004 Wiley Periodicals, Inc.
