Abstract

PURPOSE: To obtain polypropylene having a low oligomer content and an improved color, by polymerizing propylene in a vapor phase in the presence of a catalyst comprising a system prepared by pretreating a titanium trichloride composition, an organoaluminum compound and an electron-donating compound with propylene.
CONSTITUTION: In the production of polypropylene by a vapor-phase polymerization in the presence of a catalyst system contaning a titanium trichloride composition and an organoaluminum compound; said catalyst system comprises a system prepared by forming a propylene polymer by prereacting, prior to the polymerization, a catalyst consisting of a titanium trichloride composition, 0.7W20mmol, per 100g formed polypropylene, of an organoaluminum and an electron-donating compound with at least 0.01g, per g titanium trichloride composition, of propylene at a temperature ≤60°C. It is necessary that the titanium trichloride composition used has an average particle diameter of 10W100μ, pref., about 30W80μ.
