Abstract:
A polyethylene composition having the following features: 1) density from about 0.945 to about 0.955 g/cm3, determined according to ISO 1183 at 23° C.; 2) ratio MIF/MIP from about 23 to about 40; 3) MIF from about 8.5 to about 18 g/10 min.; 4) HMWcopo index from about 3.5 to about 20; and 5) long-chain branching index, LCBI, equal to or greater than about 0.45. The polyethylene composition can be used to produce pipes and films.
