Patent number: 11180581Abstract: Provided in this disclosure are organometallic complexes that contain i) a metal atom selected from Hf and Zr; 2) a phosphinimine ligand; 3) an amido-ether ligand and at least one other ancillary ligand. The use of such a complex, in combination with an activator, as an olefin polymerization catalyst is demonstrated. The catalysts are effective for the copolymerization of ethylene with an alpha olefin (such as 1-butene, 1-hexene, or 1-octene) and enable the production of high molecular weight copolymers (Mw greater than 25,000) with good comonomer incorporation at high productivity.Type: GrantFiled: April 28, 2020Date of Patent: November 23, 2021Assignee: NOVA Chemicals (International) S.A.Inventors: Darryl Morrison, P.

Publication number: 20060223960Abstract: 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.Type: ApplicationFiled: February 28, 2006Publication date: October 5, 2006Inventors: Isam Jaber, John Swabey, Xiaoliang Gao, Charles Carter, Cliff Baar
