  • Patent number: 5204303
    Abstract: The invention relates to a method for the preparation of a supported procatalyst intended for the polymerization of olefines, in which particles are formed of magnesium dihalide and alcohol, the particles are reacted with an organic compound of a metal from the groups I-III, the thus obtained particulate product is activated by means of a titanium and/or vanadium compound and optionally a donor, and optionally a prepolymerization is carried out for the activated particles. A problem of such a method is how to form particles of magnesium dihalogenide and alcohol having a structure advantageous for the polymerization of olefins. The problem has in the present invention been solved so that the particles are formed by spray crystallizing (spray freezing) a mixture of magnesium dihalide and alcohol to complex particles of magnesium dihalide and alcohol. The hydroxyl content of the particles so obtained is much greater than earlier, which results in a much more active procatalyst than the preceding ones.

  • Patent number: 5204304
    Abstract: A vanadium-containing catalyst is prepared as the product of admixing an inorganic oxide, inorganic phosphate or mixtures thereof, a zinc-containing composition, and a vanadium-containing composition. An auxiliary compound such as, for example, an aluminum halide compound may optionally be admixed. The catalyst may be combined with a co-catalyst such as an aluminum alkyl and, optionally, a halocarbon promotor to yield an olefin polymerization catalyst system. The resulting catalyst system exhibits high activity, excellent hydrogen response and produces a polymer having a narrow to broad molecular weight distribution with a bimodal profile. The catalyst is especially useful in ethylene homopolymerization and co-polymerization.
