Latest Patents

Jun Hosoi holds a patent for a groundbreaking invention titled "Continuous production method of propylene-based block copolymer." This patent outlines a process designed to ensure a stable and continuous production of the block copolymer. The method comprises several critical steps: first, polymerizing an alpha-olefin with liquid propylene in the presence of hydrogen and a stereoregular polymerization catalyst within one or more reactors. This results in a polymer slurry. Next, the slurry is transferred to a copolymerization reactor, where propylene is copolymerized with another alpha-olefin in a gaseous phase, also utilizing the stereoregular polymerization catalyst. This meticulous method not only prevents the accumulation of small diameter particles but also allows for the recycling of classified polymer slurries back into the final polymerization reactor.
