Abstract:
A polyethylene composition for producing blow-molded hollow articles, having the following features: 1) density from greater than 0.952 to 0.957 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) η 0.02  from 30,000 to 55,000 Pa·s; 5) long-chain branching index, LCBI, equal to or greater than 0.55; 6) ratio (η 0.02 /1000)/LCBI from 55 to 75.

Claim (Index 1):
A polyethylene composition having the following features:\n 1) density from greater than 0.952 to 0.957 g/cm 3  determined according to ISO 1183 at 23\u00b0 C.; 2) ratio MIF/MIP from 12 to 25, where MIF is the melt flow index at 190\u00b0 C. with a load of 21.60 kg, and MIP is the melt flow index at 190\u00b0 C. with a load of 5 kg, both determined according to ISO 1133-1; 3) MIF from 18 to 40 g/10 min.; 4) \u03b7 0.02  from 30,000 to 55,000 Pa\u00b7s; wherein \u03b7 0.02  is the complex shear viscosity at an angular frequency of 0.02 rad/s, measured with dynamic oscillatory shear in a plate-plate rotational rheometer at a temperature of 190\u00b0 C.; 5) long-chain branching index, LCBI, equal to or greater than 0.55, wherein LCBI is the ratio of the measured mean-square radius of gyration R g , measured by GPC-MALLS, to the mean-square radius of gyration for a linear PE having the same molecular weight; and 6) ratio (\u03b7 0.02 /1000)/LCBI, which is \u03b7 0.02  divided by 1000 and LCBI, from 55 to 75.
