Abstract

La présente invention concerne le domaine des mélanges hétérogènes d'élastomères. Le mélange hétérogène comprend au moins deux élastomères choisis notamment parmi les diènes conjugués, le caoutchouc naturel, le polypentène monomère, les élastomères polyoléfiniques chlores, les polysiloxanes, le caoutchouc nitrile, les copolymères du butadiene, le polyéthylène chlorosulfoné, les phosphazènes substitués, certains polyesters, les copolymères de butyle, la stabilisation de la morphologie dudit mélange hétérogène étant obtenue par irradiation dudit mélange avec une dose allant d'une valeur inférieure à la dose correspondant à la gélification jusqu'à une valeur légèrement supérieure à cette dose. Ce mélange hétérogène est notamment utile pour la fabrication de pneumatiques.
