Zusammenfassung: | Provided in this disclosure are titanium complexes that contain 1) a cyclopentadienyl ligand; 2) an adamantyl-phosphinimine ligand; and 3) at least one activatable ligand. The use of such a complex, in combination with an activator, as an olefin polymerization catalyst is demonstrated. The catalysts are effective for the copolymerization of ethylene with an alpha olefin (such as 1-butene, 1-hexene or 1-octene) and enable the production of high molecular weight copolymers (Mw greater than 25,000) at high productivity under solution polymerization conditions. |
