Abstract

Composition d'élastomères comprenant un constituant principal formé d'un premier polymère et un constituant mineur formé d'un second polymère, le premier et le second polymère ayant des températures de transition vitreuse différentes. Elle est caractérisée en ce que le premier polymère a une température de transition vitreuse peu élevée, de - 50 degrés C ou moins, et en ce que le second polymère a une température de transition vitreuse élevée, égale ou supérieure à la température ambiante. Utilisation pour la fabrication de bandes de roulement de pneumatiques.
