Abstract

La présente invention concerne : une composition de caoutchouc qui conserve des propriétés extrêmement faibles d'accumulation de chaleur et un fort allongement à la rupture et présente un excellent module à 100 % d'allongement ; un procédé de production de la composition de caoutchouc ; et un bandage pneumatique. La composition de caoutchouc de la présente invention comprend un caoutchouc à base de diène, une charge, et au moins un polymère à base de polyoléfine modifié avec un acide sélectionné dans le groupe constitué des polyéthylènes modifiés avec un acide et des polymères à base de polypropylène modifiés avec un acide, les polyéthylènes modifiés avec un acide ayant chacun une densité de 0,94 à 0,98 g/cm3 et les polymères à base de polypropylène modifiés avec un acide ayant chacun un point de fusion de 136 à 155 ºC, où la teneur du polymère à base de polyoléfine modifié avec un acide est de 1 à 30 parties en masse pour 100 parties en masse du caoutchouc à base de diène.
