A SOLID CATALYST FOR PROPYLENE POLYMERIZATION AND A METHOD FOR PREPARATION OF POLYPROPYLENE USING THE CATALYST

摘要

The present invention relates to a solid catalyst comprising: titanium; magnesium; a halogen compound; a silane-based compound; and a non-aromatic keto ester-based internal electron donor, and to a method for producing polypropylene using the same. According to the present invention, provided is a solid catalyst for polymerizing propylene, wherein the solid catalyst has excellent stereoregularity, shows a wide molecular weight distribution, and can produce polypropylene having high melt flowability in high yield.
