Supported hybrid metallocene catalyst, and method for preparing homo polyethylene using the same |
| abstract |
The present invention relates to a hybrid supported catalyst that maintains excellent catalytic activity over time and enables the production of homopolyethylene having uniform physical properties and structure, and a method for producing homopolyethylene using the same. The hybrid supported catalyst is a carrier; An alkylaluminoxane-based first cocatalyst supported on the carrier; A trialkyl aluminum-based second cocatalyst having an alkyl group having 8 or more carbon atoms supported on the first cocatalyst; And different first and second metallocene compounds supported on the second cocatalyst. |
