Abstract
(EN)
The present invention relates to a tyre for the wheels of vehicles, in particular motor vehicles, characterized by a tread comprising at least one iso-styrene/trans-butadiene elastomeric copolymer with a styrene content higher than 30% by weight with respect to the total weight of copolymer and a molecular weight higher than 500,000. Said tread is characterized by improved dynamic-mechanical behaviour at high temperatures, with higher dynamic modulus and hysteresis values, and at the same time better properties at break, optimum elasticity at low temperature and higher abrasion resistance.
(FR)
La présente invention concerne un pneumatique pour les roues de véhicules, en particulier des véhicules à moteur, caractérisé par une bande de roulement comprenant au moins un copolymère élastomère iso-styrène/trans-butadiène avec une teneur en styrène supérieure à 30 % en poids par rapport au poids total du copolymère et un poids moléculaire supérieur à 500 000. Ladite bande de roulement est caractérisée par un meilleur comportement mécanique dynamique à hautes températures, des valeurs d'hystérèse et un module dynamique plus élevés et, en même temps, de meilleures propriétés à la rupture, une élasticité optimale à basse température, et une résistance à l'abrasion plus importante.
