OLEFIN OLIGOMERIZATION CATALYST AND PROCESS EMPLOYING AND PREPARING SAME

摘要

According to the present invention, a catalyst is provided which is represented by the formula ¢RC(YR')2!2CrX, wherein R and R' are individually selected from the group consisting of carbyl and carbylsilyl groups; Y is N, C or P; and X is a halogen, halogen alkyl, Si, alkylsilyl or carbyl group. Also provided is a process for preparing the catalyst and an oligomerization process employing the catalyst. The process produces linear alpha-olefins with low amounts of polymer, vinylidine and isomerized olefins.
