Abstract

PURPOSE: To obtain a highly stereospecific poly-α-olefin, by polymerizing an α- olefin in the presence of an active titanium component, an organoaluminum compound, an electron-donating compound and an alkylaluminum compound.
CONSTITUTION: In a process for polymerizing an α-olefin in the presence of a catalyst comprising (A) an active titanium component containing Mg, a halogen, tri- or tetravalent Ti and an electron donor, (B) a trialkyl aluminum compound or an organoaluminum compound containing two or more Al atoms combined with each other through O or N, (C) an electron-donating compound and (D) an organoaluminum compound represented by the formula. Component A is first prepared, and the total component A is premixed with part to total of each of components A, B, C and d at -30W50°C in an inert solvent. Then, to a polymerization tank are introduced continuously this premix, the remaining portion of each of components B, C and D and an α-olefin and polymerized.
