PREPARATION OF OLEFIN POLYMERISATION CATALYST COMPONENT

摘要

A process for producing a Gp 2/transition metal olefin polymerisation catalyst component, in which a Gp 2 metal complex is reacted with a transition metal compound so as to produce an oil-in-oil emulsion, the disperse phase containing the preponderance of the Mg being solidified by heating to provide a catalyst component of excellent morphology. Polymerisation of olefins using a catalyst containing such a component is also disclosed. The process may be employed in the production of Ziegler-Natta catalysts.
