Patent number: 8507706Abstract: Certain metallocene compounds are provided that, when used as a component in a supported polymerization catalyst under industrially relevant polymerization conditions, afford high molar mass homo polymers or copolymers like polypropylene or propylene/ethylene copolymers without the need for any ?-branched substituent in either of the two available 2-positions of the indenyl ligands. The substituent in the 2-position of one indenyl ligand can be any radical comprising hydrogen, methyl, or any other C2-C40 hydrocarbon which is not branched in the ?-position, and the substituent in the 2-position of the other indenyl ligand can be any C4-C40 hydrocarbon radical with the proviso that this hydrocarbon radical is branched in the ?-position. This metallocene topology affords high melting point, very high molar mass homo polypropylene and very high molar mass propylene-based copolymers. The activity/productivity levels of catalysts including the metallocenes of the present invention are exceptionally high.Type: GrantFiled: September 6, 2012Date of Patent: August 13, 2013Assignee: Lummus Novolen Technology GmbHInventors: Anita Dimeska, Ralph-Dieter Maier, Nicola Stephanie Paczkowski, Matthew Grant Thorn, Andreas Winter, Joerg Schulte, Thorsten Sell
