    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; andcontacting the formed particles at least once with a transition metal halide in the presence of an electron donor.

    摘要: A novel catalyst and process for producing highly-crystalline polypropylene or pure block or terminal block types of copolymers of propylene and ethylene or propylene and another alpha-olefin in excellent yields which coproduce minor amounts of low-molecular-weight and, particularly, amorphous polymers. The catalyst comprises an aluminum alkyl compound, titanium trichloride, a sterically-hindered cyclic amine and an organotin sulfide. This novel catalyst and process are useful in polymerization techniques which use a polymerization medium or those in which the condensed monomer is polymerized from the liquid phase or those in which polymerization is accomplished from monomer substantially in the vapor phase.
