综述了近年来过渡金属配合物催化乙烯齐聚与聚合的最新进展;介绍了乙烯齐聚或聚合的反应时间、反应温度、乙烯压力、助催化剂用量等反应条件及配体上不同取代基对前过渡金属(铬,锆,钛,钒)和后过渡金属(铁,钴,镍,铜)配合物的催化活性和齐聚或聚合产物的影响;分别以钛和镍配合物催化剂为例,介绍了前过渡金属和后过渡金属催化乙烯齐聚或聚合的机理。
In this paper, the recent progress of ethylene catalyzed oligomerization and polymerization of ethylene catalyzed by transition metal complexes is reviewed. The reaction conditions of ethylene oligomerization or polymerization such as reaction time, reaction temperature, ethylene pressure and cocatalyst dosage, Catalytic activity of transition metal (chromium, zirconium, titanium and vanadium) and transition metal (iron, cobalt, nickel and copper) complexes and the influence of oligomerization or polymerization products. Taking titanium and nickel complex catalysts as examples, The mechanism of oligomerization or polymerization of ethylene catalyzed by the former transition metal and the latter transition metal.
