CATALYST FOR POLYOLEFIN POLYMERISATION AND A PRODUCTION METHOD FOR THE SAME

摘要

The present disclosure relates to a method for preparing a catalyst for polymerization of polyolefin and a catalyst for polymerization of polyolefin by using the same, and particularly, to a method for preparing a catalyst for polymerization of polyolefin, including: reacting a magnesium halide precursor solution obtained by dissolving magnesium halide in a first alcohol and a first hydrocarbon and a dialkoxy magnesium support obtained by reacting a halogen compound and a second alcohol with metal magnesium, 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 by using the above-described dialkoxy magnesium supported catalyst.
