Abstract

This invention relates to a process for the preparation of an olefin polymerization catalyst, to the use of the catalyst in olefin polymerization and to the catalyst and polymers obtained. In particular, the invention relates to the preparation of a catalyst comprising an organometallic compound of a transition metal of Group 3 to 10 of the Periodic Table (IUPAC) by a semi-continuous or continuous process.
