  • Method for the preparation of olefin polymerization catalysts
    Patent number: 7238637
    Abstract: The invention provides a process for producing an olefin polymerization catalyst comprising a catalyst component formed by contacting at least (a) a compound of Group 1 to 3 of the Periodic Table (IUPAC) with (b) a transition metal compound of Group 4 to 10 of the Periodic Table (IUPAC) or a compound of an actinide or lanthanide, in the form of solid catalyst particles, said process comprising: (1) preparing a solution from said compounds; (2) dispersing said solution to a solvent immiscible therewith and inert in relation to said compounds, to obtain an emulsion in which said solution forms the dispersed phase; and (3) solidifying the catalyst component in the dispersed droplets.
