HIGH-ACTIVITY MAGNESIUM-SUPPORTED CATALYST AND METHOD OF PREPARING POLYOLEFIN USING THE SAME |
摘要 |
A high-activity catalyst used to prepare polyethylene and a method of preparing polyolefin using the same are provided. When preparing the high-activity catalyst, a specific halogenated hydrocarbon is added to control the electrical properties of catalytic active sites and provide a large steric space around the catalytic active sites. Therefore, polyolefin with a wide range of molecular weights can be synthesized using the catalyst. |
