Cyclometallated Catalysts
A Catalyst Compound Of Formula I Or Ii: (Wherein R<1>-R<11>, M, E, T, X, Y, M And N Are Defined Herein). The Compound, When Combined With A Suitable Activator, Is Active For The Polymerization Of Olefins. In An Embodiment Of Combinations Of The R<1>-R<7 >And T Groups, These Catalysts Can Engage In Weak Attractive Non-Covalent Interactions With The Polymer Chain. In Another Embodiment, The R<1>-R<11 >Groups In Formula Ii Exhibit Weak Attractive Non-Covalent Interactions With The Polymer Chain.

Title: Cyclometallated catalysts
Usefulness: Cyclometallated catalysts
Summary: The catalyst is for use in polymerizing olefin e.g. ethylene, propylene, 1-butene, 2-pentene, 1-hexene, 1-octene, styrene, 1,3-butadiene, norbornene, each being optionally substituted. It is used in olefin polymerization processes e.g. gas, high-pressure liquid, slurry, bulk solution, and/or suspension-phase techniques.
Novelty: New polyolefin catalyst for use in polymerizing olefin e.g. ethylene, propylene, 1-butene, 2-pentene, 1-hexene, 1-octene, styrene, or 1,3-butadiene,
