摘要
The atom transfer radical polymerization (ATRP) of methyl methacrylate (MMA) was studied in the presence of ionic liquids possessing a range of counterions. Iron mediated ATRP can be carried out in the absence of added organic ligands in the presence of ionic liquids. However, copper mediated ATRP of MMA requires the presence of an added organic ligand when the ionic liquid has a halide or a carbonate anion, but not with a phosphonate anion. The ionic liquids containing transition metal salts can readily be separated from the polymerization media and regeneration of the catalyst in the ionic liquids has been successful.
