摘要：
The invention relates to a dialkoxyl magnesium carrier, which is a product produced by a reflux reaction of magnesium, an alcohol and mixed halogenated agents under an inert atmosphere. The mixed halogenated agents are iodine and magnesium chloride, and the weight ratio between iodine and magnesium chloride is 0.05:1-1:0.01. The dialkoxyl magnesium carrier is spheroid with uniform particle size distribution, excellent particle morphology and high bulk density. A solid catalyst component and a catalyst based on this carrier for olefin polymerization are also provided, and olefin polymers having a wide molecular weight distribution, good stereoregularity, excellent particle morphology and a low content of fine powders can be obtained.
