Zusammenfassung:A polyethylene composition particularly suited for producing blow-molded hollow articles, having the following features: 1) density from 0.957 to 0.968 g/cm3; 2) ratio MIF/MIP from 12 to 30; 3) MIF from 41 to 60 g/10 min.; 4) long-chain branching index, LCBI, equal to or greater than 0.45; 5) ratio (η0.02/1000)/ LCBI from 45 to 75. L'invention concerne une composition de polyéthylène particulièrement appropriée pour la production d'articles creux moulés par soufflage, ayant les caractéristiques suivantes : 1) une densité de 0,957 à 0,968 g/cm3 ; 2) un rapport MIF/MIP de 12 à 30 ; 3) un MIF de 41 à 60 g/10 min ; 4) un indice de ramification à chaîne longue, LCB1, égal ou supérieur à 0,45 ; 5) un rapport (η0,02/1000)/LCBI de 45 à 75.
