CHROMIUM SUPPORT-AGGLOMERATE-TRANSITION METAL POLYMERIZATION CATALYSTS AND PROCESSES UTILIZING SAME |
| 摘要 |
<p>The present invention is directed to a novel one-step method for forming a supported catalyst complex of high activity by substantially simultaneously contacting a bidentate or tridentate ligand forming compound, a transition metal compound and a chromium immobilized Lewis acid support-agglomerate. The catalyst can be formed prior to polymerization of olefins or within the polymerization reaction zone.</p> |
