Zusammenfassung:as described herein. Also described is a polymerization catalyst system comprising the procatalyst, a co-catalyst and optionally an external electron donor; a process of making a polyolefin by contacting an olefin with the catalyst system; a polyolefinobtained by or obtainable by the process; and a polyolefin, preferably a polypropylene, having a molecular weight distribution of between 3 and 15, a molecular weight (Mw) of between 200,000 to 1,000,000 g/mol, a melting temperature of more than 145° C., a value for the xylene solubles of less than 4 wt. % and a shaped article therefrom.
