| Abstract: | An unbridged zirconocene complex bis(1,2-diphenylcyclopentadienyl)zirconium dichloride (1,2-Ph2-C5H3)2ZrCl2] 1 has been synthesized and structurally characterized. When activated by MAO, 1 produces ultra-high molecular weight polyethylene with high melting transition temperature, as well as atactic oligopropylene with average molecular weight of ~1150 g mol-1. |
| Keywords: | Zirconium complex metallocene catalyst olefin polymerization |
