摘要: A method for producing a catalyst for the polymerization or copolymerization of olefins is described. The method includes producing a magnesium compound solution by reacting a magnesium halide compound in the mixture of a cyclic ether and two alcohols with an organosilane compound. The magnesium compound solution may be reacted with a titanium halide compound such that precipitated solid components are formed. These precipitated solid components may be reacted with a titanium compound and an electron donor to produce the polymerization catalyst.
