ETHYLENE TETRAMERIZATION CATALYSTS COMPRISING P-N-P LIGANDS |
摘要 |
A new P-N-P ligand is useful in ethylene oligomerizations. In combination with i) a source of chromium and ii) an activator such as methylalumoxane; the ligand of this invention may be used to prepare an oligomer product that contains a mixture of hexenes and octenes. The hexenes and octenes produced with this ligand contain very low levels of internal olefins when produced under preferred reaction conditions. |
