Abstract:
A halogen-containing compound as shown in a formula I can be used as a ligand for an ethylene oligomerization catalyst composition. The ethylene oligomerization catalyst composition containing the halogen-containing compound can be used to catalyze ethylene oligomerization, trimerization and tetramerization reactions. As a ligand of a catalyst for ethylene oligomerization, a fluoropolymer can effectively improve the catalytic performance of a catalyst system, and particularly exhibits improved activity and selectivity in an ethylene oligomerization reaction.
