Latest Patents

One of Hoochae Kim's latest patents is the "Bimetallic cobalt-aluminum adduct catalyst system for preparing high trans-1,4-polybutadiene." This invention focuses on polymerizing 1,3-butadiene or its derivatives in a non-polar solvent using a novel catalyst system. The catalyst system prevents gel formation, controls the molecular weight of the trans-polybutadiene, and increases the trans content of the polymer. The high oxidation state and structural stability of the cobalt-aluminum adduct enhance its reactivity, which is further optimized through innovative activation systems involving various allyloxy aluminum compounds.

Another significant patent is for "Grafted and functionalized high 1,4-trans polybutadiene with aromatic organosulfur compound." This process involves preparing 1,4-trans polybutadiene and subsequently grafting it with an aromatic organosulfur compound. The resulting polymer exhibits improved processability and tensile properties due to the minimized ultra-high molecular weight fraction and narrowed molecular weight distribution.
