Abstract
L'invention concerne un mélange in situ de premier et second copolymères d'éthylène/alpha-oléfine. L'alpha-oléfine a entre 3 et 8 atomes de carbone. Le premier copolymère a une densité comprise entre 0,9035 et 0, 908 gramme par centimètre cube et un indice de fluage à la presse à cylindres compris entre environ 1,4 gramme et environ 2,6 grammes par 10 minutes. Le second copolymère a une densité comprise entre 0,925 et 0,945 gramme par centimètre cube et un indice de fusion compris entre environ 200 et environ 400 grammes par 10 minutes. Le rapport de poids premier/second copolymère est compris entre environ 45:55 et environ 60:40, et le mélange in situ a une densité comprise entre 0,919 et 0,924 gramme par centimètre cube, un rapport de fusion compris entre environ 85 et environ 115 et un indice de fluage compris entre 65 et 90 grammes par 10 minutes.
