PREPARATION METHOD OF CATALYST FOR PRODUCING BROADER MOLECULAR WEIGHT DISTRIBUTION POLYPROPYLENE

摘要

PURPOSE: A manufacturing method of a polypropylene catalyst is provided to use the catalyst for polymerizing polypropylene with the improved workability, and the low melting point. CONSTITUTION: A manufacturing method of a polypropylene catalyst comprises the following steps: forming a deposition titanium catalyst by reacting magnesium halide, halogenated titanium, and an inside electron donor; separating the deposition titanium catalyst, washing, and drying; and reacting the deposition titanium catalyst with an organometallic compound inside a hydrocarbon solvent, to form the polypropylene catalyst.
