  • 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.

  • Publication number: 20070249799
    Abstract: A process for the preparation of a catalyst system includes the steps of combining a Lewis base, an organic compound having at least one functional group containing active hydrogen, and an organometallic component with a particulate support material to provide an intermediate composition, and then combining the intermediate composition with one or more metallocene compound. The catalyst system is advantageously used for olefin polymerization.

  • Publication number: 20050239979
    Abstract: A catalyst system includes a metallocene compound having the formula R9 L1 L2 M1R1R2 wherein R9 is a bridge between ligands L1 and L2 and M1 is a metal of Group IVB of the Periodic Table such as titanium, zirconium and hafnium and R1 and R2 can be hydrogen or aliphatic or aromatic groups. Bridge R9 can include silicon, germanium or tin. The metallocene compound of the invention as synthesized has a racemic to meso isomer ratio of greater than 5 to 1, thereby precluding the need for subsequent separation of the meso isomer.
