Abstract
A process for preparing a polyethylene resin having a multimodal molecular weight distribution in at least two loop slurry reactors connected in series can include 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. The supported metallocene catalyst can have a particle size distribution of a span value lower than 2.5 and a D50 value within the range of from 5 μm to 20 μm.
