摘要 |
<p>Magnesium chloride, titanium chloride and at least an electron donor are introduced in a plasma torch. These chlorides being in solution or in suspension in a liquid that can be an electron donor. A very fine granulometry powder is collected after cooling. The powder is very fine, it has a controlled morphology and it can be used as catalyst for alpha-olefins polymerization.</p> |
