Title: John McMeeking: Innovator in Catalysis
Introduction
John McMeeking is a notable inventor based in Calgary, Canada. He has made significant contributions to the field of catalysis, holding a total of 3 patents. His work focuses on developing innovative catalyst systems that enhance the efficiency of polymerization processes.
Latest Patents
One of McMeeking's latest patents is titled "Catalyst having a ketimide ligand." This invention describes a catalyst system that comprises an organometallic complex of a group 4 metal featuring a ketimide ligand. The complex is designed to include a cyclic ligand that forms a delocalized pi-bond with the metal, such as a cyclopentadienyl-type ligand. This system can be activated with a "substantially non-coordinating anion," resulting in a low-cost cocatalyst system that is excellent for producing olefin copolymers with both high molecular weight and very low density.
Another significant patent is "Aluminum-phosphinimine complexes as catalysts for the (co)polymerization of ethylene." In this invention, aluminum-phosphinimine complexes serve as a key component in a catalyst system for the (co)polymerization of ethylene. The catalyst components create a highly productive polymerization system when activated with "ionic activators," eliminating the need for conventional transition metal catalyst metals such as titanium, hafnium, zirconium, or vanadium.
