-
Methyl methacrylate is found to be polymerized effectively by diphenylamido-bis-(methylcyclopentadienyl) ytterbium complex (MeCp)2YbNPh2(THF). The reaction can be carried out over a wide range of temperature from -40℃ to 40℃. The polymerization activities of the ytterbocene complexes decrease with the increase of the volume of the ligand in order of MeC5H4> t-BuC5H4> Me5C5.
