A process of polymerizing ethylene or ethylene and one or more comonomers in one or more fluidized bed reactors with a catalyst system comprising (i) a supported or unsupported magnesium/titanium based precursor in slurry form, said precursor containing an electron donor; and (ii) an activator containing aluminum in an amount sufficient to essentially complete the activation of the precursor is disclosed. In the process, the precursor and the activator are mixed prior to introduction into the reactor in at least one mixing procedure, and then the mixture is contacted again with additional activator to essentially complete activation of the precursor. In the method, the atomic ratio of aluminum to titanium is in the range of about 1:1 to about 15:1 and the mole ratio of activator to electron donor is about 1:1 to about 2:1, and no additional activator is introduced into the reactor(s).

A magnesium halide composition comprising and/or made from a magnesium halide, a solvent suitable for an electron donor compound and an electron donor compound. The composition is characterized by enhanced solubility whereby it has a solubility in the solvent that does not decrease as a function of temperature up to the boiling point of the solvent and the solubility of the magnesium halide in the solvent is greater than 0. 7 mol/liter. A polymerization catalyst precursor composition can be made from magnesium halide composition by mixing the magnesium halide composition with a transition metal compound.

A spray-dried catalyst precursor composition and method of making a spray-dried catalyst precursor composition with an inert filler, magnesium, a transition metal, solvent, and one electron donor compound. The catalyst precursor composition is substantially free of other electron donor compounds, the molar ratio of the electron donor compound to magnesium is less than or equal to 1. 9, and comprises spherical or substantially spherical particles having a particle size of from about 10 to about 200 μm. Catalysts made from the spray-dried catalyst precursors and polymerization methods using such catalysts are disclosed.

Polyethylene resins having improved environmental stress crack resistance, stiffness and impact resistance is made by a process comprising feeding both a chromium oxide catalyst and a silyl chromium catalyst into a polymerization reactor. The chromium oxide catalyst and the silyl chromium catalyst are on separate supports. The chromium oxide catalyst is 25–50 weight percent and the silyl chromium catalyst is 50–75 weight percent of the total weight of catalyst. The catalysts may be added separately or as a single mixture.

Methods of preparing a polymerization catalyst component is provided, in which a magnesium component, a Lewis acid solubilizing component, a titanium compound, optionally a transition metal compound different than the titanium compound, and typically an inert filler are combined in a slurrying agent and spray-dried to produce a catalyst precursor in the form of a substantially spherical and porous solid particle. The methods and catalysts of this disclosure can provide ethylene homopolymer and copolymer resins having a high molecular weight tail and a broadened molecular weight distribution as compared to more traditional Ziegler-Natta catalysts.

The invention teaches a novel design for a fluidized bed polymerization reactor which utilizes a primary fluidization grid to provide mixing and fluidization of the polymer and at least one secondary distribution plate located above the first distribution plate to promote segregation of polymer particles by size, the larger particles falling into the lower fluidization zone and the smaller particles being entrained up from the primary fluidization grid and through the secondary distribution grid into an upper reaction zone.
