Horst Wei? has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Transition metal compound, ligand system, catalyst system and its use for the polymerization and copolymerization of olefins
    Patent number: 7569651
    Abstract: A process for the polymerization of olefins, in particular a process for the copolymerization of propylene with further olefins, is carried out in the presence of highly active catalyst systems comprising specifically selected metallocenes, in particular ones which bear different substituents in position 2 and position 4 on an indenyl ligand. Novel polypropylene copolymers can be obtained by this process.
    Type: Grant
    Filed: May 18, 2005
    Date of Patent: August 4, 2009
    Assignee: Basell Polypropylen GmbH
    Inventors: Jörg Schottek, Markus Oberhoff, Carsten Bingel, David Fischer, Horst Weiβ, Andreas Winter, Volker Fraaije, Ralph-Dieter Maier, Wolfgang Bidell, Nicola Paczkowski, Jürgen Suhm, Roland Kratzer
