具有弱亲电性的Ni原子与含孤对电子(如O、N、P等)的化合物配位所得的Ni配合物可以用于催化乙烯聚合,因其良好的稳定性和极性功能基团容忍性的优点,成为乙烯聚合用后过渡金属催化剂研究的热点之一。Ni配合物催化乙烯聚合的研究不仅有利于探索乙烯聚合机理模型,而且对设计具有高选择性乙烯聚合Ni催化剂具有建设性意义。笔者从Ni配合物配体的位阻效应和电子效应对其催化乙烯聚合活性和聚合产物特性影响方面,综述了近5年Ni配合物在乙烯聚合方面的研究进展,详细阐述了Ni配合物中取代基的位阻效应和电子效应的影响规律,并展望了Ni配合物在乙烯聚合领域的发展前景。

T he polymerization of ethylene can be catalyzed by the Ni complexes in w hich the Ni atom of weak electroplicity is coordinated by the O ,N ,P‐containing compounds with lone pair of electrons .Recently ,the Ni complexes have become one of the hot topics in the transition metal researching field for ethylene polymerization ,due to their good stability and the tolerance to the polar functional groups . The research of Ni complexes for ethylene polymerization not only is beneficial to the model exploration for ethylene polymerization mechanism , but also has a constructive sense on designing Ni catalysts of high selectivity for ethylene polymerization .The research progress of Ni complexes based on the ethylene polymerization in recent five years was reviewed about the steric and electronic effects of ligands on the activity and characteristics of polymerization products .The rules of the steric and electronic effects of the substituent groups on the Ni complexes were discussed in detail ,as well as the prospect of Ni complexes .
