CATALYST COMPOSITION AND PROCESS FOR PREPARING LINEAR ALPHA-OLEFINS

摘要

The present invention relates to a catalyst composition for the oligomerization of ethylene, comprising a transition metal compound of the general formula MX m(OR')4-m or MX m(OOCR')4-m, wherein R' is an alkyl, alkenyl, aryl, aralkyl or cycloalkyl group, X is chlorine or bromine and m is from O to 4 and a reaction product of an organoaluminium compound and a cyclic amide, preferably 2- pyrolidone, as well as to a process for preparing linear alpha-olefms utilizing this catalyst composition.
