Title (EN) ETHYLENE COPOLYMER COMPOSITION
(FR) COMPOSITION COPOLYMÈRE D'ÉTHYLÈNE
Abstract:
(EN) The pipe articles with excellent stress crack resistance can be achieved by providing ethylene copolymer composition comprises ethylene and a C6-C10 α -olefin comonomer; the ethylene copolymer having a total density of 0.945-0.980 g/cm3 and a MFR5 of 0.10-0.50 g/10 miri; and the ethylene copolymer having a comonomer content of 1-5 % wt. The ethylene copolymer has Mx/My in the range of not less than 14.0; gpcBR in the range of from 0.20 to 0.80; and strain hardening modulus in the range of not less than 53.4.
(FR) L'invention concerne des articles de tuyau dotés d'une excellente résistance aux fissures de contrainte pouvant être obtenus par fourniture d'une composition copolymère d'éthylène comprenant de l'éthylène et un comonomère d'α-oléfine en C6-C10; le copolymère d'éthylène présentant une densité totale de 0,945 à 0,980 g/cm3 et un indice de fluidité à chaud MFR5 allant de 0,10 à 0,50 g/10 miri; et le copolymère d'éthylène ayant une teneur en comonomère de 1 à 5 % en poids. Le copolymère d'éthylène présente une relation Mx/My comprise dans la plage non inférieure à 14,0; un indice gpcBR compris dans la plage allant de 0,20 à 0,80; et un module de durcissement par écrouissage compris dans la plage non inférieure à 53,4.
