Latest Patents

One of his latest patents is a process for preparing polyethylene. This innovative method involves producing polyethylene compositions using a catalytic system of ethylene polymerizing catalyst and cocatalyst in a multistage continuous reaction sequence. The process begins with the polymerization of ethylene, hydrogen, and comonomers in a first loop reactor. The reaction mixture is then transferred to a second loop reactor for continued polymerization. Finally, the mixture is moved to a gas phase reactor to form the end product. The residence time and reaction temperature are carefully controlled to ensure that the proportion of ethylene polymer produced in the first loop reactor to the end product is between 1-20%.
