Abstract
A carrier for an olefin polymerization catalyst contains a magnesium-containing compound and sulfur. The sulfur is at least one of an elemental sulfur, a complex sulfur, and a compound sulfur. The carrier has good particle morphology and a smooth surface, and has a narrow particle size distribution. The catalyst prepared from the carrier has high activity and good sensitivity to hydrogen regulation, and can improve the density of a polymer stack when being used for olefin polymerization.
