Zusammenfassung:A polyethylene composition particularly suited for producing blow-molded hollow articles, having the following features: 1) density from 0.945 to 0.958 g/cm3, determined according to ISO 1183 at 23°C; 2) ratio MIF/MI10 from 2 to 10; 3) η0.02 from 200,000 to 800,000 Pa.s; 4) LCBI equal to or lower than 0.80; 5) ratio (η0.02/1000)/ LCBI equal to or greater than 350. L'invention concerne une composition de polyéthylène particulièrement adaptée à la production d'articles creux moulés par soufflage, présentant les caractéristiques suivantes : 1) une masse volumique de 0,945 à 0,958 g/cm3, déterminée selon la norme ISO 1183 à 23 °C ; 2) un rapport MIF/MI10 de 2 à 10 ; 3) un η0.02 de 200 000 à 800 000 Pa.s ; 4) un LCBI inférieur ou égal à 0,80 ; 5) un rapport (η0.02/1000)/ LCBI supérieur ou égal à 350.
