Title: Innovations in Olefin Polymerization: The Contributions of Barbara M Tsuie
Introduction
Barbara M Tsuie is an accomplished inventor based in Cincinnati, OH. With a remarkable portfolio of 19 patents, she has significantly advanced the field of polymer chemistry, particularly in olefin polymerization processes.
Latest Patents
Among her latest innovations is a novel olefin polymerization process that utilizes a slurry approach for polymerizing ethylene. This process involves polymerizing ethylene in the presence of an α-olefin and a catalyst that includes an activator and a supported bridged indeno[1,2-b]indolyl zirconium complex. The resulting polyethylene demonstrates excellent incorporation of the α-olefin and exhibits low long-chain branching. Furthermore, this process excels in producing high-molecular-weight polyethylene and shows impressive hydrogen sensitivity. Another notable patent from Tsuie describes a similar slurry process where ethylene is polymerized in a first reactor with hydrogen. The catalyst features a supported dimethylsilyl-bridged indeno[1,2-b]indolyl zirconium complex, leading to the production of an ethylene homopolymer. The process allows for the formation of polyethylene with superior properties, including a weight-average molecular weight greater than 150,000 and enhanced environmental stress crack resistance, suitable for pipes and molded articles.
