Catalyst/Cocatalyst Nuclearity Effects in Single-Site Polymerization. Enhanced Polyethylene Branching and α-Olefin Comonomer Enchainment in Polymerizations Mediated by Binuclear Catalysts and Cocatalysts via a New Enchainment Pathway

The binuclear “constrained geometry catalyst” (CGC) (μ-CH2CH2-3,3‘){(η5-indenyl )[1-Me2Si( t BuN)](ZrMe2)}2 [EBICGC(ZrMe2)2; Zr 2 ] and the trityl bisborate dianion (Ph3C+)2[1,4-(C6F5)3BC6F4B(C6F5)3]2- (B 2 ) have been synthesized to serve as new types of multicenter homogeneous olefin polymerizatio...
