Abstract

PURPOSE: To obtain polypropylene improved in % formation of amorphous polymer by-products, polymerization activity and particle properties, by polymerizing propylene in the presence of an alkyl ether-treated titanium trichloride and a dialkylaluminum.
CONSTITUTION: In a process for polymerizing propylene alone or together with other olefins copolymerizable therewith in the presence of a catalyst consisting of a combination of (A) titanium trichloride obtained by reducing titanium tetrachloride with metallic aluminum or an organoaluminum compound, treating the product with a complexing agent and further contacting the product with titanium tetrachloride and (B) a dialkylaluminum monochloride, titanium trichloride is pretreated with 0.01W4 times by mol of an alkyl ether. A preferred complexing agent is a monoether of about 8W12C, for example, butyl ether, isoamyl ether or octyl ether.
