Abstract:
A polyethylene composition for producing blow-molded hollow articles, having the following features: 1) density from greater than 0.957 to 0.965 g/cm 3 , determined according to ISO 1183-1 at 23° C.; 2) ratio MIF/MIP from 12 to 25; 3) MIF from 18 to 40 g/10 min.; 4) Mw equal to or greater than 230,000 g/mol; 5) η 0.02  from 35,000 to 55,000 Pa·s; 6) long-chain branching index, LCBI, equal to or greater than 0.55; and 7) ratio (η 0.02 /1000)/LCBI from 55 to 75.

Claim (Index 10):
The process of  claim 9 , comprising the polymerization steps, in any mutual order:\n a) polymerizing ethylene, optionally together with one or more comonomers, in a gas-phase reactor in the presence of hydrogen; and b) copolymerizing ethylene with one or more comonomers in another gas-phase reactor in the presence of an amount of hydrogen less than step a); wherein, in at least one of the gas-phase reactors, the growing polymer particles flow upward through a first polymerization zone (riser) under fast fluidization or transport conditions, leave the riser and enter a second polymerization zone through which the growing polymer particles flow downward under the action of gravity, leave the second polymerization zone and are reintroduced into the first polymerization zone, thereby establishing a circulation of polymer between the two polymerization zones.
