CATALYST FOR PROPYLENE POLYMERIZATION AND THE METHOD OF PROPYLENE POLYMERIZATION USING THE CATALYST

摘要

The present invention provides a catalyst for propylene polymerization and a method for propylene polymerization using the same, specifically, a catalyst for propylene polymerization, which is prepared by reacting dialkoxy magnesium with titanium halide compound or silane halide compound and internal electron donor in the presence of an organic solvent, and a method for propylene polymerization which can produce polypropylene having 99% or more of iso- tacticity index, by mixing and reacting said catalyst, alkyl aluminum, external electron donor and propylene.
