摘要： The present invention provides a magnesium-based solid and a solid catalyst component for olefin polymerization. By means of determination based on a nitrogen adsorption method, the solid has a multimodal pore distribution and a specific surface area of not less than 50 m 2 /g, and the pore size distribution of the solid is in a range of 1 nm to 300 nm. There is at least one peak within a pore size range of less than 10 nm, and there is at least another peak within a pore size range of not less than 10 nm. When the catalyst formed using the solid catalyst component is used for propylene polymerization, the catalyst has higher polymerization activity and higher stereotactic orientation capability, and the prepared polymer has a relatively wide molecular weight distribution.

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.
