Latest Patents
One of his latest patents is titled "Elastic terpolymer including diene group and preparation method thereof." This invention relates to an elastic terpolymer that achieves excellent processability and elasticity simultaneously. The elastic terpolymer is a copolymer composed of 40 to 70 weight % of ethylene, 15 to 55 weight % of a C-Calpha-olefin, and 0.5 to 20 weight % of a diene, produced in the presence of a group 4 transition metal catalyst. The weight average molecular weight of the terpolymer, measured by GPC, ranges from 100,000 to 500,000. Additionally, the difference between the tan δ values at angular frequencies of 0.2 rad/s and 100.0 rad/s is 0.5 or less, measured at 100°C using a rubber process analyzer.
Another notable patent is focused on the method of preparing the elastic terpolymer. This method optimizes the energy efficiency of the entire process while copolymerizing an ethylene/alpha-olefin/diene-based elastic copolymer. The process includes separating and removing the solvent and unreacted monomers from the polymer solution, utilizing a gas-liquid separator and a stripper for purification.
