Title
(EN) TYRE COMPRISING A CYCLOOLEFIN POLYMER, TREAD BAND AND ELASTOMERIC COMPOSITION USED THEREIN
(FR) PNEUMATIQUE CONTENANT UN POLYMERE CYCLO-OLEFINIQUE, BANDE DE ROULEMENT ET COMPOSITION D'ELASTOMERE CORRESPONDANTE
Abstract
(EN)
Tyre for vehicle wheels, comprising at least one component made of a crosslinked elastomeric material, in which said component includes an elastomeric composition comprising: (a) at least one diene elastomeric polymer; (b) at least one cycloolefin polymer, said cycloolefin polymer having a glass transition temperature (Tg) of not less than 50 °C. Preferably, said component including said composition is a tyre tread band.
(FR)
L'invention concerne un pneumatique pour roues de véhicule comprenant au moins un composant constitué d'un matériau élastomère réticulé, dans lequel ce composant comprend: (a) au moins un polymère élastomère diénique, (b) au moins un polymère cyclo-oléfinique, ce polymère cyclo-oléfinique possédant une température de transition vitreuse (Tg) supérieure à 50 °C. Ce composant, comprenant cette composition, est de préférence une bande de roulement de pneumatique.
