Abstract
The invention relates to supports comprising inorganic oxide particles coated with magnesium chloride and a method for making them. The inorganic oxide has a mean particle diameter of less than 5 microns and is used as a seed to crystallize magnesium chloride from solution. The magnesium chloride-coated inorganic oxide is useful for supporting transition metal compounds; the supported transition metal compounds are used as catalysts for polymerizing olefins.
Claims9
A support comprising inorganic oxide particles coated with magnesium chloride wherein the particles have a mean diameter less than 5 microns and the weight ratio of magnesium chloride to inorganic oxide is from about 1,000:1 to about 100,000:1.
