Title: Koshi Matsubara and His Ethylene Copolymer Invention.
Introduction
Koshi Matsubara is an inventor associated with Yokkaichi, Japan, and Mitsubishi Petrochemical Company Limited. His recorded patent work includes an invention focused on ethylene copolymers and their production.
Latest Patents
Matsubara is credited with 1 patent: “Ethylene Copolymer and Method of Producing Same.” The invention describes producing a copolymer through radical polymerization of ethylene and specified vinyl compounds under high pressure and elevated temperatures. The vinyl compound makes up less than 1 mol% of the combined monomers, and the patent specifies that at least 83% of its units are bonded between ethylene units in the polymer chain. The resulting copolymer has a melt flow rate of 0.1 to 200 g/10 min and is designed to provide effective light stabilization despite containing only a small amount of the vinyl compound.
Career Highlights
Matsubara’s listed patent connects his inventive work with Mitsubishi Petrochemical Company Limited. The patent’s focus is a polymer composition and manufacturing method intended to combine low vinyl-compound content with photo-stabilizing performance.
Collaborations
Yoshikazu Higaki and Hajime Ikeno are identified as Matsubara’s coworkers.
Conclusion
Koshi Matsubara’s recorded invention addresses the production of photo-stabilizing ethylene copolymers, reflecting a specific contribution to polymer technology.
