    Abstract: 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.

    Abstract translation: 本发明的领域一般涉及制备非常高或超高分子量聚乙烯的方法。 更具体地说,本发明涉及使用包含载体,活化剂和金属 - 配体络合物的负载催化剂以及催化剂本身制备非常高或超高分子量聚乙烯的方法。 本发明还涉及使用包含载体,活化剂和共支持的金属 - 配体络合物的负载催化剂以获得聚乙烯的双峰分子量分布的方法。
