Abstract:
The present invention discloses an olefin polymerisation process carried out in the presence of a Ziegler-Natta catalyst in two liquid full loop reactors connected in series wherein different molecular weight fractions are produced to form a polyolefin, said process being characterized in that the Ziegler-Natta catalyst has a particle size distribution d50 of less than 20 μm and greater that 5 μm.
