Abstract: A polyethylene composition particularly suited for producing blow-molded hollow articles, having the following features:



1) density from 0.948 to 0.955 g/cm3;
2) ratio MIF/MIE from 60 to 120;
3) MIF from 15 to 45 g/10 min.;
4) ER values from 2 to 5.0;

said composition being obtainable by contacting a precursor polyethylene composition with a radical initiator.

Abstract: Embodiments of the present disclosure relate to a method of preparing polyethylene compositions comprising polymerizing ethylene in a first gas-phase reactor and polymerizing ethylene in a second gas-phase reactor in the presence of hydrogen; wherein at least one of the first or second gas-phase reactors comprises a first and second polymerization zone; wherein a hydrogen pressure of the first and second polymerization zones are different such that at least a portion of the second ethylene cycles through the first and second polymerization zones and a gas mixture of each polymerization zone is partially or totally prevented from entering the other zone.
