Title: Akira Kimura and a Controlled Polyalkylene Oxide Production Method.
Introduction
Akira Kimura is an inventor associated with Himeji, Japan, and Sumitomo Seika Chemicals Co., Ltd. His patent work concerns a method for producing polyalkylene oxide with molecular weight and polydispersity controlled within a desired range.
Latest Patents
Kimura is credited with 1 patent, titled “Method for Producing Polyalkylene Oxide.” The disclosed method first polymerizes an alkylene oxide in the presence of a chain transfer agent to produce a high-molecular-weight polyalkylene oxide. It then irradiates that material to obtain the resulting polyalkylene oxide. The method specifies a chain transfer agent amount of at least 800 mass ppm relative to the alkylene oxide and a viscosity of no more than 6,000 mPa·s for a 1 mass percent aqueous solution of the high-molecular-weight polymer.
Career Highlights
The patent describes a production approach intended to control polymer properties through a combination of polymerization conditions and radiation treatment. Kimura’s listed company affiliation is Sumitomo Seika Chemicals Co., Ltd.
Collaborations
Yuika Imamura is identified as Kimura’s coworker. The provided information does not specify a particular joint patent or project between them.
Conclusion
Akira Kimura’s listed invention presents a method for producing polyalkylene oxide with controlled molecular weight and polydispersity through polymerization followed by radiation treatment.
