Abstract

In this study, the binuclear constrained geometry catalyst (CGC) (3,3′-μ-CH₂CH₂) {n⁵-indenyl) [1-SiMe₂(^tBuN)] (ZrMe₂)}₂ [EBI(CGCZrMe₂)₂ (Zr₂) and trityl bisborate (Ph₃(C⁺)₂[1,4-(C₆F₅)₃BC₆F₄ B(C₆F₅)₃]^2-(B₂) were synthesized and characterized to serve as new types of binuclear single-site Ziegler-Natta catalysts and cocatalysts for olefin polymerization. The monometallic metallocene complex (3-CH₂CH₃-indenyl) [1-SiMe₂(^tBuN)]ZrMe₂ (Zr₁) was synthesized as a control for studies of cooperativity in ethylene polymerization. Polymerization studies show that these catalysts and cocatalysts are highly active in mediating ethylene polymerization.
