Photoinduced atom transfer radical polymerization of methyl methacrylate initiated by in situ generation of copper (I) complex from higher oxidation state species using neat zinc oxide and iron-doped zinc oxide nanoparticles is investigated. The polymerizations proceed in a well-controlled manner under UV light at room temperature as evidenced by kinetic and light on–off experiments. The evolution of molecular weight with conversion shows good correlations between experimental and theoretical molecular weights, which confi rmed good control over polymerization along with a narrow molecular weight distribution.
