Abstract

In the invention, improved isotacticity and melt processability of poly-α-olefins have been achieved by means of a novel polymerization and a catalyst system therefor. The catalyst system has been prepared by a process in which magnesium dichloride or a complex thereof, titanium tetrachloride, and internal donor, a first organoaluminium compound, and an external donor are contacted to form a contacting product. The contacting product is then contacted with a second organoaluminium compound which, on an atom basis, contains more halogen per aluminium than the first organoaluminium compound.
