Patent number: 6239061Abstract: Aluminum-phosphinimine complexes function as a component in a catalyst system for the (co)polymerization of ethylene. The inventive catalyst components form a highly productive polymerization system when activated with so-called “ionic activators”. The need for conventional transition metal catalyst metals (such as titanium, hafnium, zirconium or vanadium) is eliminated.Type: GrantFiled: November 23, 1999Date of Patent: May 29, 2001Assignee: Nova Chemicals (International) S.A.Inventors: Qinyan Wang, Xiaoliang Gao, John McMeeking, Wei Xu, Douglas W.

Patent number: 6153550Abstract: The invention relates to a catalyst composition for olefin polymerization comprising metallocene complexes and novel cocatalysts belonging to the group of perfluorinated oligoarylaluminates, oligoarylthioaluminates and oligoarylaminoaluminates. These cocatalysts are produced by two alternative synthetic methods, either by reacting alkylalumoxanes with pentafluorophenol, pentafluorothiophenol, or with pentafluoroaniline, respectively; or in two-step processes comprising first reacting trialkylaluminum compounds with said perfluorinated agents and then by reacting the products of the first step with water. Catalyst systems containing these cocatalysts and metallocene complexes are active in polymerization and copolymerization reactions of ethylene and alpha-olefins.Type: GrantFiled: December 18, 1997Date of Patent: November 28, 2000Assignee: Mobile Oil CorporationInventor: Yury V Kissin
