Title: The Innovative Contributions of Makoto Sone
Introduction
Makoto Sone is a prominent inventor based in Mie-ken, Japan. He has made significant contributions to the field of polymer chemistry, particularly in the production of olefin polymers and copolymers. With a total of six patents to his name, Sone's work has advanced the understanding and application of polymerization processes.
Latest Patents
One of Sone's latest patents is a process for the production of olefin polymer. This innovative process involves the polymerization of ethylene and/or α-olefin with three or more carbons at a polymerization temperature of not lower than 120°C. The catalyst used in this process comprises a specific metallocene compound with a substituted fluorenyl group, along with a compound that reacts with the metallocene to form a cationic metallocene compound. The resulting olefin polymer or copolymer exhibits narrow composition distribution, narrow molecular weight distribution, and a high molecular weight.
Another notable patent by Sone is for producing an ethylene/α-olefin copolymer. This process involves the copolymerization of ethylene with an α-olefin having three or more carbons, utilizing an olefin polymerization catalyst at a polymerization temperature of not lower than 120°C. The catalyst consists of a metallocene compound containing hafnium, an ionizing ionic compound, and an organoaluminum compound. The ionizing ionic compound is crucial as it transforms the metallocene compound into a cationic form without further reacting with it.
