PROCESS FOR PRODUCING A CATALYST COMPONENT FOR POLYMERIZATION OF OLEFINS |
摘要 |
<p>A process for producing a catalyst component for polymerization of olefins which comprises contacting (a) a metal oxide with (b) an organomagnesium compound represented by the formula RMgR' wherein R denotes a hydrocarbyl group and R' denotes a hydrocarbyl group or a halogen atom, contacting the resulting contacting product with (c) carbon dioxide, and further contacting the resulting contact product with (d) a titanium compound. Optionally, the carbon dioxide contacted contact product can be treated with the halogen-containing compound prior to contact with the titanium compound.</p> |
