  • Patent number: 8034886
    Abstract: The present invention relates to a process of manufacturing high, very high, and ultra high molecular weight polymers comprising predominantly ethylene monomers. Ethylene is reacted in the presence of a catalyst system to produce a polymer having a viscosimetrically-determined molecular weight of at least 0.7×106 g/mol. The catalyst system generally includes a bridged metallocene catalyst compound, optionally with a co-catalyst. The catalyst is characterized by a zirconium dichloride central functionality and a dimethyl silandiyl bridge between five-membered rings of indenyl groups. Both rings of the metallocene compound are substituted at the 2-position with respect to the dimethyl silandiyl bridge with a C1-C20 carbonaceous group.

  • 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.

  • Patent number: 7468416
    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: 20080027175
    Abstract: The present invention relates to novel polymers, which are based on poly(vinyl ester) copolymers and poly(vinyl alcohol) copolymers having excellent thermal properties because of their special composition and to the use of said polymers. The poly(vinyl alcohol-polyalkene) copolymers and polymer mixtures obtained in this way are characterized by a strongly modified melting behavior compared to linear poly(vinyl alcohols).

  • Patent number: 7285608
    Abstract: A catalyst system includes a metallocene compound having the formula R9 L1 L2 M1 R1 R2 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.
