Abstract:
A method for making a solid catalyst component for use in a Ziegler-Natta catalyst, the method comprising the steps of:a) combining a porous particulate support with a magnesium source in a hydrocarbon solvent to form a slurry mixture, the magnesium source including a hydrocarbon soluble organomagnesium compound and hydrocarbon insoluble inorganic magnesium-halogen compound; b) halogenating the organomagnesium compound; and, c) reacting the slurry mixture with a titanium compound or vanadium compound to form the solid catalyst component wherein the ratio of total moles of magnesium in the magnesium source to the moles of the porous particulate support ranges from about 0.1:1 to about 10:1.
