摘要：
The present invention relates to a catalyst for synthesizing a polypropylene with a wide molecular weight distribution and use of the same. The catalyst comprises magnesium halide, titanium-containing compound, and an organic phosphate type electron donor compound. By the catalyst according to the present invention, a propylene polymer with a wide molecular weight distribution, easily controllable isotacticity and good processing properties can be synthesized.
