  • Thermally tunable phosphinimine catalysts
    Patent number: 10570222
    Abstract: A new phosphinimine polymerization catalyst exhibits restricted rotation about a carbon-phosphorous bond. The restricted rotation is demonstrated using variable temperature 1H NMR. Ethylene copolymers made using the catalysts have microstructures which are dependent on the temperature at which polymerization takes place.

  • 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.
