    摘要: A process for producing a Gp IIa/transition metal olefin polymerisation catalyst component, in which a Gp IIa 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.

    摘要: Process for preparing an olefin polymerisation catalyst component comprising magnesium halide, titanium halide and a carboxylic acid ester electron donor, in which the precursors of its constituents are reacted in solution from which the component is eventually precipitated, this precipitation being accompanied by co-precipitation of one or more oligoesters of the carboxylic acid formed in a controlled manner. The component is employed, together with an organometallic co-catalyst, for polymerisation of C 2 -C 10 α-olefins.
