METHOD FOR PRODUCING VERY-HIGH OR ULTRA-HIGH MOLECULAR WEIGHT POLYETHYLENE |
摘要 |
The field of the invention relates generally to a method for preparing very-high or ultra-high molecular weight polyethylene. More particularly, the present invention related to a method of preparing very-high or ultra-high molecular weight polyethylene using a supported catalyst comprising a support, an activator and a metal-ligand complex, as well as the catalyst itself. The present invention additionally relates to a method of using a supported catalyst comprising a support, an activator and co-supported metal-ligand complexes to obtain a bi-modal molecular weight distribution of polyethylene. The supported catalyst has a structure of: (see formula) |
