Morphology-controlled olefin polymerization catalyst formed from an emulsion |
摘要 |
A solid, hydrocarbon-insoluble, olefin-polymerization catalyst component having substantially uniform particles useful in polymerizing olefins is formed by: reacting a magnesium-containing compound with carbon dioxide or sulfur dioxide; forming a two-phase mixture of the resulting magnesium-containing compound with a suitable liquid hydrocarbon-miscible phase and a suitable polar solvent phase; forming particles by adding the two-phase mixture after vigorous agitation to a liquid hydrocarbon; and contacting the formed particles at least once with a transition metal halide in the presence of an electron donor.
