Latest Patents

Zhou Chen holds a patent for "Metallocene catalysts for polyethylene." This patent discloses metallocene compounds and catalyst compositions that comprise a metallocene compound. The processes for polymerizing olefins, methods for making catalyst compositions, olefin polymers, and articles made from olefin polymers are also detailed in this patent. Notably, the metallocene compounds contain a fluorenyl ligand and a cyclopentadienyl ligand bridged by a linking group. The cyclopentadienyl ligand is characterized by being substituted with a C-C heterohydrocarbyl group, with an oxygen atom positioned five atoms distance or less from the cyclopentadienyl ligand. Additionally, the linking group features a pendant C-C alkenyl group with a terminal C=C double bond. This innovative catalyst composition can produce polyethylene with a low melt index without the need for a second metallocene.
