Abstract:
The invention relates to a process for the production of bimodal polyethylene in a two-step polymerization process in the presence of a catalyst system comprising: (I) the solid reaction product obtained by reacting of: a) a hydrocarbon solution containing 1) an organic oxygen containing magnesium compound or a halogen containing magnesium compound and 2) an organic oxygen containing titanium compound and b) an aluminum halogenide having the formula AIRnX3-n in which R is a hydrocarbon radical containing 1-10 carbon atoms, X is halogen and 0
