Process for the preparation of a Ziegler-Natta type catalyst. |
| 摘要 |
<p>The present invention relates to a process for the preparation of a Ziegler-Natta type catalyst having a granular support. The process comprises contacting the granular support with (a) an organosilicon compound, (b) a dialkylmagnesium and optionally a trialkylaluminium compound, (c) a monochloro-organic compound, and (d) with at least one tetravalent titanium compound. According to the invention the organosilicon compound can be a silane such as diethoxydimethylsilane, methyltrimethoxysilane, methyltriethoxysilane or tetraethoxysilane. It can also be a disilazane such as hexamethyldisilazane.</p> |
