| titleOfInvention | Catalyst for ethylene homopolymerization or copolymerization and preparation method thereof |
| abstract | The invention belongs to the technical field of catalysts, and particularly relates to a catalyst for ethylene homopolymerization or copolymerization and a preparation method thereof. The components are as follows: a titanium-containing active component, an activator component; the titanium-containing active component: fumed oxides, magnesium dihalides, titanium halides, electron donor compounds, modifiers and structure modifiers; the active component is AlR n X 3‑n The organic aluminum compound, R is a hydrocarbyl with 1-20 carbon atoms, X is halogen, n is a number which is more than 1 and less than or equal to 3, and is specifically one of triethyl aluminum, triisobutyl aluminum, tri-n-hexyl aluminum, tri-n-octyl aluminum or diethyl aluminum monochloride. The improver is tetra-n-butoxy silane; the structural modifier is absolute ethyl alcohol. The catalyst has high catalytic efficiency and the preparation process is relatively simple. |
