    摘要: The present invention relates to a high activity olefin polymerization catalyst comprising a boron-containing silica support and the preparation thereof. This invention is characterized in that the support is heat treated in combination with a chemical treatment using a boron compound. The boron compound used in the chemical treatment of this invention is boron halide, preferably boron trichloride. The catalyst of this invention has the weight of boron comparing with the support is 0.5 to 0.7% and has the weight of the boron relative to the catalyst of 0.1 to 0.5%. The catalyst of this invention has chemical compositions comprising:—Boron 0.1-0.5% wt;—Titanium 4-6% wt;—Magnesium 2-6% wt;—Chloride 15-25% wt.
