Abstract:
1. A process for the preparation of olefin polymerisation catalyst comprising an organometallic compound of a transition metal of Group 3 to 10 of the Periodic Table (IUPAC), or of an actinide or lanthanide, in the form of solid particles comprising: (a) preparing a liquid/liquid emulsion comprising at least two phases, wherein a solution of catalyst component(s) in a solvent forms the dispersed phase in the form of droplets and a liquid medium immiscible therewith forms the continuous phase; said continuous phase being inert to the components of the catalyst solution; (b) solidifying said droplets from said dispersed phase, and optionally (c) isolating said catalyst, wherein at least step (b) is carried out continuously.
