苯氧基亚胺型非茂单活性中心催化剂

摘要

The effects of catalyst structure, role of substituents, selection of co - catalysts and immobilization technology on the activity of phenoxy - imine non - metallocene single - site catalyst was reviewed with 27 references. The results showed that the performance of phenoxy - imine non - metallocene catalyst could be controlled by selecting substituents of compounds. Using an appropriate amount of triethyl-enealuminum as co - catalyst, its polymerization activity could be comparable to that using methylalu-minumoxane as co - catalyst. Moreover, the catalyst support and immobilization method played an important role in the polymerization activity of the catalyst.%从催化剂结构、取代基作用、助催化剂选择和负载化技术对苯氧基亚胺型非茂单活性中心催化活性的影响进行了综述.结果表明,通过改变配合物中取代基的性能,可以实现对催化剂性能的调控.以三乙基铝为助催化剂,通过调控其用量,可以使其催化活性达到以MAO为助催化剂的水平.另外,载体的类型和负载方式对催化剂的活性也有一定的影响.
