Zusammenfassung:	The present invention relates to a process for preparing a polyethylene resin having a multimodal molecular weight distribution in at least two loop slurry reactors connected in series comprising the step of: polymerizing ethylene in the presence of at least one supported metallocene catalyst a diluent optionally one or more co monomers and optionally hydrogen thereby obtaining the polyethylene resin wherein the supported metallocene catalyst has a particle size distributionof a span value lower than 2.5 and a D50 value within the range of from 5 µm to 20 µm.
