Abstract
Disclosed is a method for preparing a catalyst for polymerization of polyolefin. The preparation method according to the present disclosure includes a) dissolving a magnesium halide compound in a first alcohol and a first hydrocarbon and then adding an alkoxysilane compound thereto to prepare a magnesium halide precursor solution; b) reacting a second alcohol with metal magnesium in the presence of a halogen compound to prepare a dialkoxy magnesium support; and c) reacting the magnesium halide precursor solution and the dialkoxy magnesium support with titanium tetrachloride and an internal electron donor in the presence of a second hydrocarbon. The present disclosure may provide a catalyst for polymerization of two-component magnesium compound supported polyolefin showing high activity.
