Catalyst for ethylene polymerization and method for producing polyethylene |
| abstract |
PROBLEM TO BE SOLVED: To provide a catalyst system capable of producing a high-density polyethylene having a practically sufficient high molecular weight in an industrially practical temperature range of 70 ° C to 90 ° C in slurry polymerization. The zirconocene compound comprises an activator, and the zirconocene compound has an ethylene insertion reactivity parameter (ΔE ins (kJ / mol)) and a polymer chain desorption reactivity parameter (ΔE elm (kJ / mol)). And (E) preferably satisfy the condition of ΔE ins ≦ 0.8 (ΔE elm ) −13 (I) ΔE ins ≦ 0.8 (ΔE elm ) −25 (II) And a method for producing polyethylene using the catalyst. |
