| titleOfInvention | Method for producing polypropylene |
| abstract | (57) [Abstract] [PROBLEMS] To provide a method for obtaining a polypropylene having high rigidity and a low catalytic activity in a multi-stage polymerization of propylene, having good processability. [Structure] Propylene is multi-stage polymerized using a polymerization catalyst component obtained by the following 1) to 3), And a method for producing polypropylene, which comprises varying the melt flow rate of the polymer obtained at each stage. 1) A polymerization catalyst component obtained by bringing activated titanium trichloride into contact with 2) an alkenyl group-containing alkoxysilane in the presence of an organoaluminum compound. |
