METHOD FOR PREPARING A SOLID CATALYST FOR THE POLYMERIZATION OF POLYPROPYLENE WITH HIGH ACTIVITY AND APPARENT DENSITY, AND THE SOLID CATALYST PREPARED USING THE METHOD

摘要

PURPOSE: A method for preparing a solid catalyst for the polymerization of polypropylene is provided to prepare a solid catalyst for the polymerization of polypropylene with high activity through a simple manufacturing process. ;CONSTITUTION: A method for preparing a solid catalyst comprises the steps of: (i) reacting magnesium halide compounds with alcohols, adding phthalic acid compounds to prepare a magnesium compound solution; (ii) mixing aliphatic or cycloaliphatic hydrocarbon solvent with aromatic hydrocarbon solvents to prepare a mixed solvent, dispersing a titanium compound in the mixed solvent, reacting with the magnesium compound solution, and heating the reactant to prepare a supporter; and (iii) reacting the supporter with titanium compounds and electron donors to obtain a solid product.;COPYRIGHT KIPO 2011
