FIELD: chemistry.
SUBSTANCE: invention relates to a solid catalyst component for olefin polymerization, which comprises the reaction products of a dialkoxy magnesium carrier, a titanium compound and electron donor compound in an inert solvent. Also provided is a dialkoxy magnesium carrier, which is a product obtained by reacting magnesium, mixed alcohols, and mixed halogenated agents in inert atmosphere feedback vapor condensation, wherein mixed halogenated agents are iodine and magnesium chloride. Furthermore, a catalyst for olefin polymerization based on said solid catalyst component.
EFFECT: present invention provides the possibility of obtaining olefin polymers having a broad molecular weight distribution, good stereoregularity and good particle morphology, low fine powders.
