| 摘要 |
This invention relates to single site catalyst supportation methods involving high temperature treatment (≥ 40°C, e.g., 100-130°C) to improve catalyst activity for olefin polymerization, e.g., propylene polymerization, and to the supported catalyst systems obtained by the methods, e.g., single site catalyst systems supported on a support having high average particle size (PS ≥ 30 μm), high surface area (SA ≥ 200 m2/g), low pore volume (PV ≤ 2 mL/g), and a mean pore diameter range of 1 ≤ PD ≤ 20 nm. |
