| 抄録: | In this work, the influences of the Ti oxidation state on the catalytic properties of MgCl_2-supported Ziegler–Natta catalysts in ethylene homo- and co-polymerization with 1-hexene. Three catalysts having different Ti oxidation states were synthesized by milling TiCl_4, TiCl_3, or TiCl_2 together with MgCl_2. With these catalysts having different Ti oxidation states, the polymerization conditions such as the Al concentration, temperature, and 1-hexene concentration were varied to figure out their catalytic abilities in ethylene homo- and co-polymerization. The Ti oxidation state affected the catalyst activity largely, having unique dependences on the polymerization conditions. A higher oxidation state led to a higher activity, slightly larger comonomer incorporation, and lower molecular weight as well as its narrower distribution. However, rough characteristics of copolymers were similar among the different Ti oxidation states. |
