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.

Abstract: A solid, spheroidal polymerization catalyst having a particle size distribution characterized by a Dm*/Dn of less than 3.0, the catalyst comprising a phosphinimine catalyst, a cocatalyst and a magnesium chloride support. A process for the polymerization of ethylene with one or more alpha olefin catalyzed by a solid, spheroidal polymerization catalyst having a particle size distribution characterized by a Dm*/Dn of less than 3.0, the catalyst comprising a phosphinimine catalyst, a cocatalyst and a magnesium chloride support.

Abstract: A process for controlling the placement of alpha olefins within an ethylene copolymer. The process involves polymerizing ethylene and an alpha olefin in the gas phase while changing the breadth of control over the molar ratio of ethylene to comonomer and/or hydrogen which is being fed to a polymerization reactor. At tighter control breadths, the alpha olefin may be incorporated mainly in the higher molecular weight portions of the ethylene copolymer. At looser control breadths, the alpha olefin may be incorporated more evenly throughout the ethylene copolymer or mainly in the lower molecular weight portions of the ethylene copolymer.
