ABSTRACT:
In the invention a procatalyst of a catalyst system of a new type intended for the polymerization of olefins has been prepared comprising a carrier based on a magnesium compound, a titanium compound and a dialkylester of phthalic acid. The most important properties of this kind of a procatalyst are the high stereoselectivity and the high activity. Now it has been possible to increase the activity considerably by using a different kind of dialkylester of phthalic acid having in its alkyl 9 to 20 carbon atoms and the dielectricity constant of which being preferably below 5 measured at 25 C.
