Process for producing alpha-olefin oligomer compositions
摘要
A process for preparing an alpha -olefin oligomer which comprises oligomerizing an alpha -olefin in a solvent in the presence of a chromium-based catalyst system comprising a combination of at least a chromium compound, an amine or metal amide, and an alkylaluminium compound, in a contacting mode that the chromium compound and the alkylaluminium compound are not previously contacted with each other.
