α-二亚胺镍、钯络合物和吡啶二亚胺铁、钴络合物是近几年来发现的新一代烯烃均相聚合后过渡金属催化剂。这类催化剂具有活性高、选择性易调变、聚合物性质可控制的特点 ,尤其是对官能团中的杂原子的稳定性方面优于前过渡金属催化剂。本文将近年来的有关报道归纳为 4个方面进行评述 :络合物的合成和结构 ;配体结构因素对络合物催化性能的影响 ;催化烯烃高聚、齐聚和共聚以及催化反应机理。 α-diimine nickel, palladium complex and pyridine diimine iron, cobalt complex is a new generation of heterogeneous transition metal catalyst for olefin polymerization found in recent years. These catalysts have the characteristics of high activity, easy to adjust the selectivity and controllable properties of the polymer, especially superior to the front transition metal catalyst for the stability of the heteroatoms in the functional groups. In this paper, the reports in recent years are summed up in four aspects: the synthesis and structure of the complex; the influence of the ligand structure on the catalytic performance of the complex; the mechanism of olefin polymerization, oligomerization and copolymerization as well as the catalytic reaction.
