  Bridge length effect of new dinuclear constrained geometry catalysts on controlling the polymerization behaviors of ethylene/styrene copolymerization

  摘要：

  According to the observable evidence from H-1 and C-13 nuclear magnetic resonance and mass spectrometry, new dinuclear constrained geometry catalysts (DCGCs) with a structure of [{Ti(eta(5):eta(1)-(C9H5)Si (CH3)(2)(NBu)-Bu-t)Cl-2(CH2)(n)}(2)(C6H4)] [n = 0 (10), n = 1 (11), n = 2 (12)] were synthesized successfully. Copolymerization of ethylene and styrene were tested by using three new DCGCs and Dow CGC. The catalyst activity, the molecular weight (MW) and styrene content of the copolymers were sharply improved as the bridge structure was transformed from para-phenyl (10) to para-xylyl (11) and para-diethylenephenyl (12). The activity of 11 and 12 was about four to five times greater than that of 10 regardless of the polymerization conditions. In addition, the capability to form high MW polymers increased in the order of Dow CGC approximate to 10 < 11 < 12. The styrene contents in copolymers generated by 11 and 12 were higher than those of 10. (C) 2010 Elsevier Ltd. All rights reserved.

  2-bis(1-indenyl)benzenes in 29–45% yield. New phenyl-bridged ansa-bis(indenyl)titanium and -zirconium dichlorides were obtained from these ligands in good yield either by addition of TiCl3 or ZrCl4 to their lithium salts (61–92% yield) or by addition of Zr(NMe2)4 to the neutral ligands (59–67%). In each case the zirconium tetraamide metalation gave very high dl-selectivity. The n-BuLi/ZrCl4 metalation
