Summary: | The present invention relates to a polyethylene composition comprising 1) contacting, in a first gas phase fluidized bed reactor, a gaseous composition, a supported titanium magnesium catalyst precursor and co-catalyst. The HMW polymer produced is transferred to a second gas phase fluidized bed reactor together with a further gaseous composition. The resulting polymer blend product is then melted in an extruder and then passed through one or more active screens. |
