Synthesis of 4-arm methyl methacrylate star polymer by atom transfer radical polymerization
The synthesis of 4-arm methyl methacrylate star polymer had been achieved successfully by atom transfer radical polymerization using CuCl as catalyst, 2, 2¢- bipyridyl as ligand and pentaerythritol tetrakis (2-bromoisobutyrate) as the initiator. The star polymer was characterized by 1H-NMR and GPC, by which the precise 4-arm structure of the PMMA was confirmed.
