  • Publication number: 20060293474
    Abstract: This invention relates to a process to polymerize olefins comprising contacting, in a polymerization system, olefins having three or more carbon atoms with a catalyst compound, activator, optionally comonomer, and optionally diluent or solvent, at a temperature above the cloud point temperature of the polymerization system and a pressure no lower than 10 MPa below the cloud point pressure of the polymerization system, where the polymerization system comprises any comonomer present, any diluent or solvent present, the polymer product, where the olefins having three or more carbon atoms are present at 40 weight % or more, wherein the metallocene catalyst compound is represented by the formula: where M is a transition metal selected from group 4 of the periodic table; each R1 is independently selected from the group consisting of hydrogen, hydrocarbyl, substituted hydrocarbyl and functional group, and any two R1 groups may be linked, provided that if the two R1 groups are linked, then they do not form a but

  • Publication number: 20060247399
    Abstract: The present invention provides a method of producing oligomers of olefins, comprising reacting olefins with a catalyst under oligomerization conditions. The catalyst can be the product of the combination of a chromium compound and a heteroaryl-amine compound. In particular embodiments, the catalyst compound can be used to trimerize or tetramerize ethylene to 1-hexene, 1-octene, or mixtures of 1-hexene and 1-octene.

  • Publication number: 20050250956
    Abstract: The present invention relates to ligands and the synthesis of those ligands for use in metallocene complexes. More particularly, the present invention relates to the synthesis of diarylsilyl bridged biscyclopentadienes using diarylsilyldisulfonates. Even more particularly, the present invention describes Group IV metallocenes containing diarylsilyl bridged bis-cyclopentadienyl ligands prepared from contacting a diarylsilyldisulfonate with an organometallic indenyl reagent.

  • Publication number: 20050049436
    Abstract: Non-coordinating anions or anion precursors are disclosed. These non-coordinating anions serve as the activator for olefin polymerization catalyst systems. As such, they abstract an alkyl leaving group from a metallocene catalyst precursor leaving an activated catalyst charge balanced by a non-coordinating anion. These anions are formed by 3 or 4 partially fluorinated naphthyl ligands coordinated around boron (or other Group-13 element) creating corresponding tris-borane or tetrakis-borate complexes.
