摘要
简要介绍了新型的烯烃聚合催化剂—Ni(Ⅱ )、Pd(Ⅱ )、Fe(Ⅱ )、Co(Ⅱ )类后过渡金属催化剂的发展、特点及催化乙烯聚合机理 ,并就它们的组成结构、聚合条件和配体体积对聚合产物结构。
The novel catalysts for ethylene polymerization,late transition metal catalysts based on Ni(Ⅱ),Pd(Ⅱ) incorporating α- diimine ligands and Fe(Ⅱ),Co(Ⅱ)incorprating pyridine diimine ligands have been reviewed. Their composition and structure、the mechanism of catalysis for ethylene polymerization、the influence of their ligands bulk and reaction conditions for the polymerization have been discussed respectively according to the difference of their ligands.
