Latest Patents

One of Eiji Tanaka's most recent innovations is a continuous production method of propylene-based block copolymer. This groundbreaking process allows for stable and long-lasting production of a propylene-based block copolymer, minimizing the accumulation of small-diameter particles. The method involves several key steps: polymerizing an α-olefin with liquid propylene as the main component in the presence of hydrogen and a stereoregular polymerization catalyst to create a polymer slurry, followed by feeding this slurry into a copolymerization reactor. In this reactor, propylene and an α-olefin, distinct from propylene, are copolymerized in a gaseous phase, alongside the stereoregular polymerization catalyst and a deactivating compound, resulting in a propylene-block copolymer powder. Notably, the polymer slurry can be classified to recycle smaller particles back into the system for optimized production efficiency.
