首次用简单的锂基催化剂Lu(CH2SiMe3)3(THF)x(Py)2-x(x=0，1，2)催化2-乙烯基吡啶的聚合反应获得了良好的等选择性(Mmm>；99%)和高活性(TOF>；4000 h-1)。等色素
Excellent isoselectivity (mmmm > 99%) and high activity (TOF > 4000 h–1) were achieved for the first time in the polymerization of the polar 2-vinylpyridine by using the simple lutetium-based catalysts, Lu(CH2SiMe3)3(THF)x(Py)2–x (x = 0, 1, 2). The isosel
