| abstract |
The invention relates to a process for the preparation of an olefin polymerization catalyst component, as well as a polymerization catalyst component and its use. In the process, a magnesium compound containing an alkoxy moiety, a dicarboxylic acid dihalide, and a titanium tetrahalide are reacted with each other. Good activity can be obtained easily by adding a reactive halogenated hydrocarbon during the process. |
