Patent ID: 8901261

Claim:
Process for preparing a particulate olefin polymerisation catalyst component said process comprising the steps of: a) providing a solution of at least one Complex A being a complex of a Group 2 metal compound and a monohydric alcohol comprising in addition to the hydroxyl moiety at least one further oxygen bearing moiety being different to a hydroxyl moiety optionally in an organic liquid reaction medium; b) adding said solution to at least one compound of a transition metal and producing an emulsion the dispersed phase of which contains more than 50-mol % of the Group 2 metal; c) agitating the emulsion in order to maintain the droplets of said dispersed phase preferably within an average size range of 5 to 200 μm; d) solidifying said droplets of the dispersed phase; e) recovering the solidified particles of the olefin polymerization catalyst component, and wherein an electron donor is added at any step prior to step c) and said electron donor is non-phthalic acid ester.
