Abstract

A spheric magnesium compound comprises a reaction product of at least the following components: (a) a magnesium halide having a formula of MgX2-nRn, wherein X is independently chloride or bromide, R is a C1-C14 alkyl, a C6-C14 aryl, a C1-C14 alkoxy, or a C6-C14 aryloxy, and n is 0 or 1; (b) an alcohol compound; and (c) an epoxy compound having a general formula (I), wherein R2 and R3 are independently hydrogen, a C1-C5 linear or branched alkyl, or a C1-C5 linear or branched haloalkyl. The magnesium compound has characteristic DSC curve and X-ray diffraction pattern, and can be used as a carrier for olefin polymerization catalyst.
