  • Self supported phosphinimine catalyst
    Patent number: 10336841
    Abstract: In some embodiments provided herein is a self-supported phosphinimine single site catalyst having a molar ratio of Al from the activator (MAO) to the active metal in the catalyst from 5:1 to 30:1. The catalyst is prepared by precipitating an emulsion of the activated catalyst from a perfluoroalkane continuous phase resulting in spherical catalyst particles having a diameter typically from 5 to 200 ?m.
    Type: Grant
    Filed: February 21, 2017
    Date of Patent: July 2, 2019
    Assignee: NOVA Chemicals (International) S.A.

  • Process for polymerization using dense and spherical ziegler-natta type catalyst
    Patent number: 9963526
    Abstract: Some embodiments herein disclose a process for producing an ethylene polymer or copolymer which contains less than 5 ppm titanium and has a bulk density, in granular form, of at least 22.5 lbs/ft3, using a spheroidal Ziegler-Natta type olefin polymerization catalyst having a particle size distribution characterized by a Dm*/Dn of less than 3.0 and comprising a titanium compound, an aluminum compound, and a spheroidal magnesium chloride support.

  • Passivated supports for use with olefin polymerization catalysts
    Patent number: 9359455
    Abstract: A phosphinimine catalyst immobilized on a passivated inorganic oxide support, had high activity at low co-catalyst concentrations and gave, under gas phase polymerization conditions, ethylene copolymer with a high molecular weight. A method of making a passivated silica support involves treatment of silica with an organoaluminum compound, a diorganomagnesium compound and a source of chloride (to make MgCl2) under anhydrous conditions and in the absence of polar solvents.
