Method of preparing a catalytic composition for dimerization, co-dimerization and oligomerization of olefins

摘要

The present invention describes a method of preparing a catalytic composition used for oligomerization, co-dimerization or polymerization of olefins, wherein the compound obtained upon contacting at least one iron compound with at least one nitrogen-containing compound is subjected to an oxidation stage prior to being mixed with an activating agent and optionally with a solvent.;The present invention also describes the catalytic composition obtained by means of said preparation method and the use thereof for oligomerization, co-dimerization or polymerization of olefins.
