Abstract

PURPOSE: To prepare polypropylene having a high specific gravity with a low atactic polypropylene content in a high yield per unit weight of catalyst, by polymerizing propylene partially and subsequently, using a speficic catalyst.
CONSTITUTION: Prpylene is partially polymerized by using a catalyst comprising one mole of a highly active titanium trichloride and obout 2W20 moles of a dialkylauminum monochloride at about -10W90°C and 10-2W10 kg/cm2 to give a polymer in an amount of about 1W500 grams per gram of TiCl3. The resulting prepolymer composition is then incoporated with about 2W20 times the molar amount of TiCl3 of a dialkylaluminum monochloride and about 0.1W2 times the molar amount of a ≥2C trialkylamine, and subsequently polymerized by adding propylene at about 50W100°C and 1W100 kg/cm2. Polymer can be obtained in a yield of 10,000 or more times the unit weight of TiCl3.
