Abstract:
The invention is directed to bimodal polyethylene having a flow ratio FRR ranging between ≥30 and ≤40, a density ranging between ≥949.0 and ≤952.0 kg/m3, an MFR 190/5  ranging between ≥0.1 and ≤0.2 g/10 min and comprising from 50 to 54% by weight of an ethylene homopolymer A and from 46-50% by weight of an ethylene-butene copolymer B, where all percentages are based on the total weight of the composition and wherein ethylene homopolymer A has a viscosity number ≥70 and ≤100 cm3/g and a density between ≥968 and ≤972 kg/m3. The polyethylene is suitable to be applied in the production of pipes.

Claim (Index 5):
A process for the preparation of bimodal polyethylene according to  claim 1  with a two-step slurry polymerisation process in the presence of a catalyst system comprising\n (I) the solid reaction product obtained from the reaction of:\n a) a hydrocarbon solution containing\n 1) an organic oxygen containing magnesium compound or a halogen containing magnesium compound, and \n 2) an organic oxygen containing titanium compound and \n \n b) an aluminium halogenide having the formula AlR n X 3-n  in which R is a hydrocarbon moiety containing 1-10 carbon atoms, X is halogen and 0<n<3, and \n \n (II) an aluminium compound having the formula AlR 3  in which R is a hydrocarbon moiety containing 1-10 carbon atoms.
