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 5):
The polyethylene composition of  claim 1 , having at least one of the following additional features:\n comonomer content equal to or less than 0.3% by weight with respect to the total weight of the composition; HMWcopo index from 0.1 to 3; wherein the HMWcopo index is determined according to the following formula:\n HMWcopo =(\u03b7 0.02 \u00d7t maxDSC )/(10{circumflex over (\u2003)}5) \n wherein \u03b7 0.02  is the complex viscosity of the melt in Pa\u00b7s, measured at a temperature of 190\u00b0 C., in a parallel-plate rheometer under dynamic oscillatory shear mode with an applied angular frequency of 0.02 rad/s; tmaxDSC is the time, in minutes, to reach the maximum value of heat flow (in mW) of crystallization (time at which the maximum crystallization rate is achieved, equivalent to the t\u00bd crystallization half-time) at a temperature of 124\u00b0 C. under quiescent conditions, measured in isothermal mode in a differential scanning calorimetry apparatus, DSC; and LCBI is the ratio of the measured mean-square radius of gyration Rg, measured by GPC-MALLS, to the mean-square radius of gyration for a linear PE having the same molecular weight at a mol. weight of 1,000,000 g/mol.
