Abstract

E' altamente desiderabile che i battistrada di pneumatici presentino buone caratteristiche di trazione, per esempio buona resistenza allo slittamento ad umido. Tuttavia, è stato tradizionalmente molto difficile perfezionare le caratteristiche di trazione di uno pneumatico senza sacrificare la resistenza al rotolamento e la usura del battistrada. Gli elastomeri a segmenti ad alte prestazioni secondo la presente invenzione offrono una combinazione speciale di caratteristiche desiderabili per la utilizzazione nella fabbricazione di composizioni per pneumatici di battistrada. Per esempio, i polimeri gommosi secondo la presente invenzione possono essere lavorati in modo da ottenere battistrada per pneumatici che presentano sorprendenti caratteristiche di trazione, mantenendo nello stesso tempo una buona resistenza di rotolamento ed una buona durata del battistrada. La presente invenzione più specificamente espone un polimero gommoso che presenta una eccellente combinazione di proprietà per l'impiego nella fabbricazione di battistrada per pneumatici, consistente di unità ricorrenti che sono derivate essenzialmente da almeno un monomero dienico coniugato, in cui il primo segmento presenta un peso molecolare medio numerico che rientra nell'intervallo fra circa 25.000 e circa 350.000; e da un segmento finale
