CATALYST COMPOSITION AND PROCESS FOR OLIGOMERIZATION OF ETHYLENE

摘要

PROBLEM TO BE SOLVED: To provide a catalyst composition having an improved activity and an improved selectivity, for the preparation of linear low molecular weight alpha olefins preferably with an improved C-Cfraction yield.SOLUTION: The present invention relates to a catalyst composition for the oligomerization of ethylene, comprising at least one transition metal bisphenolate compound and at least one cocatalyst. The transition metal bisphenolate is a zirconium bisphenolate. The invention also relates to a process for the oligomerization of ethylene in the presence of the catalyst composition according to the invention. The process results in a high yield of C-Clinear alpha-olefin and C-Clinear alpha-olefin.
