Bridged Bis(Indenyl) Transitional Metal Complexes, Production, and Use Thereof

摘要

The invention relates to a novel group bridged metallocene transition metal complexes, wherein the complex includes at least one indenyl ligand substituted at the 4-position with a phenyl group, the 4-phenyl group being preferably substituted at the 3′, 4′, and 5′ positions with particular combinations of substituents, particularly wherein the 4′-substituent is a group of the formula (XR′n)−, wherein X is a Group 14-17 heteroatom having an atomic weight of 13 to 79 and R′ is one of a hydrogen atom, halogen atom, a C1-C10 alkyl group, or a C6-C10 aryl group and n is 0, 1, 2, or 3. Catalyst systems including the transition metal complex, polymerization processes using the transition metal complex, and polymers made using the transition metal complex are also described.
