Abstract
The characteristics of late transition metal catalysts relative to early transition metal catalysts in the catalytic polymerization of olefins are simply described.Late transition metal catalysts with several types of ligands are introduced and the factors affecting the catalyst thermostability are summarized by comparing the relative molecular mass of the obtained polymers,the catalytic activity for olefin polymerization and the sustainable time of the activity.In general,the proper adjustment of the steric hindrance and electronic effect of the ligands toward the metal centers and a rational design of ligand structure can effectively improve the thermostability of the late transition metal catalysts.关键词
