Abstract

El presente invento se refiere a una llanta para las ruedas de vehículos, en particular vehículos de motor, caracterizada por una banda de rodamiento que consta al menos de un copolímero elastomérico de iso-estireno/trans-butadieno con un contenido de estireno más alto que 30% en peso con respecto al peso total del copolímero y un peso molecular más alto que 500,000. La banda de rodamiento se caracteriza por el comportamiento mecánico dinámico mejorado a altas temperaturas, con valores más altos de módulo dinámico e histéresis y al mismo tiempo, mejores propiedades en la rotura, óptima elasticidad a baja temperatura y resistencia más alta a la abrasión.
