Carrier for olefin polymerization catalysts |
摘要 |
<p>Procedure for the preparation of a solid carrier for olefin polymerization catalysts, comprising the steps: a) impregnating a silica with a solution of Mg-chloride in the presence of electron donors, b) drying the impregnated silica obtained in (a) and impregnating it with a solution of Mg-alkyls in SiCl4 at a temperature from -10 to 20 <o>C, optionally adding a further amount of electron donors, c) subsequently treating the slurry obtained in (b) at a temperature from 40 <o>C to reflux temperature, d) drying the carrier obtained in (c). The carrier which is obtained according to the above procedure is advantageously used for the preparation of supported catalysts for the polymerization of olefins.</p> |
