Abstract

L'invention concerne un nouveau caoutchouc copolymère d'isoprène-butadiène. Ce caoutchouc copolymère comprend une microstructure de la partie butadiène ayant de 70 à 90 % de liaison trans-1,4 et de 2 à 8 % de liaison vinyle, une teneur en isoprène comprise entre 3 et 25 % en poids et une teneur en styrène comprise entre 0 et 30 % en poids, ledit caoutchouc copolymère ayant une viscosité Mooney comprise entre 30 et 150, une distribution de poids moléculaire Mw/Mn comprise entre 1,2 et 3,5, ledit caoutchouc, à l'état non allongé, ne présentant pas de point de fusion mesuré par la méthode d'analyse calorimétrique différentielle par balayage. Ce caoutchouc copolymère présente des meilleures propriétés de traitement que les produits correspondants antérieurs.
