Abstract A novel method for iron‐mediated atom transfer radical polymerization with activators generated by electron transfer (AGET) ATRP of a polar monomer, methyl methacrylate (MMA), is developed in the presence of catalytic amounts of inorganic base NaHCO 3 or Na 2 CO 3 . The polymerization is carried out using FeCl 3 · 6H 2 O as the catalyst, triphenylphosphine as the ligand, ethyl 2‐bromoisobutyrate as the initiator, and vitamin C as the reducing agent at 70 °C. It is found that the addition of base into the polymerization system enhances the polymerization rate significantly but does not destroy the controllability over the molecular weight and molar‐mass dispersity.
