Abstract: front page image
(EN)An ethylene/α-olefin copolymer which comprises monomer units derived from ethylene and monomer units derived from an α-olefin having 3 to 20 carbon atoms and which has a density (d) of 860 to 950kg/m3, a melt flow rate (MFR) of 0.05 to 100g/10min, a ratio of weight-average molecular weight (Mw) to number-average molecular weight (Mn), (Mw/Mn), of 2 to 10, a swelling ratio (SR) of less than 1.35, and a g* of 0.50 to 0.75.
(FR)L'invention concerne un copolymère éthylène/α-oléfine qui comprend des unités monomères dérivées d'éthylène et des unités monomères dérivées d'une α-oléfine contenant 3 à 20 atomes de carbone et qui a une densité (d) de 860 à 950 kg/m3, un indice de fluidité (MFR) de 0,05 à 100 g/10 min, un rapport entre le poids moléculaire moyen en poids (Mw) et le poids moléculaire moyen en nombre (Mn), (Mw/Mn), de 2 à 10, un taux de gonflement (SR) inférieur à 1,35 et un g* de 0,50 à 0,75.
