Abstract

The initiators for continuous activator regeneration atom transfer radical polymerization (ICAR ATRP) of methyl methacrylate (MMA) was successfully carried out in N,N-dimethyl formamide (DMF) at ambient temperature under irradiation with N,N,N′,N′-tetramethyl–1,2-ethanediamine (TMEDA) as ligand, azobisisobutyronitrile (AIBN) as photoinitiator, and CCl4 as initiator. The polymerization obeyed the first-order kinetics. Linear increase of the molecular weight distribution (MWD) with monomer conversion and narrow molecular weight distribution were observed. The polymerization proceeded in a living fashion at 15 °C. The apparent activation energy (Eapp) of 27.23 kJ/mol was obtained based on the slope of the plot of ln (kapp) versus (1/T) and the enthalpy (∆Heq 0) was 5.08 kJ/mol. The polymerization was controlled by periodic light on-off. The living character of polymerization was further demonstrated by chain extension with the resulting PMMA-Cl as macrointiator.
