  • Heat management in ethylene oligomerization
    Patent number: 10160696
    Abstract: The oligomerization of ethylene using a chromium catalyst having a heteroatomic ligand may be used to provide oligomerization products that are selective towards hexene and/or octene. However, such processes also typically produce some polymer as an undesirable by product. The present invention is directed towards improvements in the selective oligomerization of ethylene.

  • Activation for Oligomerization
    Publication number: 20120271087
    Abstract: The oligomerization of ethylene using a chromium catalyst and an aluminoxane activator is well known. The undesired formation of polyethylene as a by-product is also known to occur during prior oligomerization processes. We have discovered that the use of an aluminoxane that is prepared by non-hydrolytic means provides a highly productive activator (co-catalyst) for ethylene oligomerization and mitigates the undesired formation of by-product polyethylene.

  • Ethylene oligomerization
    Publication number: 20120101321
    Abstract: The oligomerization of ethylene using a chromium catalyst having a bridged diphosphine ligand can produce a selective product distribution (to predominantly hexene or predominantly octene/hexene) when activated with an aluminoxane. The oligomerization reaction also produces polymer by product—particularly when the aluminoxane is provided in a non-aromatic solvent. The present invention mitigates this problem.

  • Polymer mitigation
    Publication number: 20110257350
    Abstract: Ethylene is selectively oligomerized in a continuously stirred tank reactor (CSTR) that is preferably operated in an isothermal manner using a chromium catalyst. The undesired formation of by-product polyethylene is mitigated by contacting the ethylene with hydrogen prior to adding the ethylene to the reactor and feeding the ethylene and hydrogen via a common feed port.

  • Borate activator
    Patent number: 7214744
    Abstract: A catalyst system comprising (i) a bulky ligand catalyst compound; and (ii) a novel borate activator is active for olefin polymerization. The novel borate contains at least one chelating (divalent) ligand and contains at least one fluorine atom. Preferred borate activators are provided as anilinium or carbonium salts. Highly preferred borate salts contain two perfluorinated alkoxy chelating ligands. The catalyst system may be used to produce polyethylene for “end use” applications such as polyethylene film and molded polyethylene goods.

  • Modified (MAO + aluminum alkyl) activator
    Publication number: 20060223960
    Abstract: A cocatalyst system for olefin polymerization comprises an aluminoxane (especially methylaluminoxane, or “MAO”), an aluminum alkyl and a halogenated phenol. The preferred halogenated phenol is pentafluorophenol. The use of pentafluorophenol permits the substitution of a portion of the MAO cocatalyst (which is expensive) with inexpensive aluminum alkyl. The cocatalyst is most preferably employed in combination with an organometallic catalyst having at lease one pi ligand.
