Abstract
A spherical carrier for olefin polymerization catalysts has at least one magnesium-containing compound having a structure represented by formula (1). The spherical carrier has a relatively good particle morphology, and substantially no abnormally morphological particles will appear. A method for preparing the spherical carrier can be used to prepare a carrier having a small particle size and greatly expands the particle size range of the preparable carrier. When the catalyst prepared by using the carrier is used for olefin polymerization, polymerization activity is good, substantially no abnormally morphological material is present, and hydrogen response is good.
