摘要：
Bis(2-pyridinal)ethylenediimine was used as a ligand for copper-mediated atom transfer radical polymerization (ATRP) of methyl methacrylate. Reactions were performed at molar ratios of monomer:initiator:catalyst of 100:1:0.5 and catalyst:ligand ratios of 1:1 and 1:2. Polymerization reactions were performed in bulk as well as in the presence of polar solvents such as dimethylformamide and acetonitrile. Reactions carried out in bulk resulted in polymerizations with poor control due to the low solubility of the copper complex in the monomer. The control was however improved by carrying out the reactions in solution using either dimethylformamide or acetonitrile as solvent. (C) 2003 Society of Chemical Industry.
