titleOfInvention | Method for producing polypropylene |
abstract | (57) Abstract: To produce polypropylene having high stereoregularity and high rigidity and an improved elastic modulus, crystals added in excess by finely dispersing a crystal nucleating agent in polypropylene. Provided is a method for producing polypropylene capable of reducing a nucleating agent. SOLUTION: (A) (a) a solid component containing magnesium, titanium, a halogen, and an electron-donating compound as essential components is added in the presence of (b) an organoaluminum compound: , A solid catalyst component obtained by performing the prepolymerization steps in that order, a step of polymerizing propylene, a step of polymerizing vinylcycloalkane, a step of polymerizing propylene in the presence of a specific alkyltrialkoxysilane (B ) A method for producing polypropylene, which comprises polymerizing propylene using a polymerization catalyst comprising an organoaluminum compound and (C) an electron-donating compound. |
