摘要
Methyl methacrylate (MMA) was effectively polymerized by diphenylamido bis(methylcyclopentadienyl) ytterbium complex (MeCp)2 YbNPh2 (THF). The reaction can be carried out over a range of polymerization temperature from - 40°C to 40°C and gives me polyMMA with high molecular weights. The initiation mechanism was demonstrated by diphenylamido-terminated methyl methacrylate oligomer.
