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 contacting a solid catalyst component containing a metal oxide, magnesium, titanium, a halogen and an electron donating compound as an essential component with 2) an organoaluminum compound and 3) an alkenyl group-containing alkoxysilane. |
