METHOD FOR PREPARING SOLID TITANIUM CATALYST FOR OLEFIN POLYMERIZATION

摘要

PURPOSE: Provided is a method for preparing a solid titanium catalyst for olefin polymerization, which represents high activity and high stereo-regularity by controlling the particle size and shape of the catalyst. CONSTITUTION: The method for preparing a solid titanium catalyst for olefin polymerization comprises the steps of: (1) dissolving a magnesium halide compound in a mixed solvent containing at least one alcohol and/or oxygen-containing compound to form a magnesium compound solution; (2) reacting the magnesium compound solution with an organic acid halide compound to form a carrier; and (3) reacting the carrier with a titanium compound to form a solid titanium catalyst for olefin polymerization.
