Olefin polymerization catalyst. |
摘要 |
<p>A solid hydrocarbon-insoluble, alpha-olefin polymerization catalyst component with superior activity, stereo-specificity and morphology characteristics comprises the product formed by A) forming a solution of a magnesium-containing species from a magnesium carbonate or a magnesium carboxylate; B) precipitating solid particles from such magnesium-containing solution by treatment with a transition metal halide and an organosilane; C) reprecipitating such solid particles from a mixture containing a cyclic ether; and D) treating the reprecipitated particles with a transition metal compound and an electron donor.</p> |
