The present invention relates to a composition for elastomeric compounds for tyres, the composition comprising a modified diene polymer (A1) terminated with at least one tetrazole group (E) comprising at least one 2, 5-disubstituted tetrazole, which can be activated by heating, and tyre parts and tyres for vehicle wheels comprising them. Advantageously, the modified diene polymer (A1) of the present invention imparts a lower thermal hysteresis and a reduced Pearn effect, thus lower rolling resistance and wear. In addition, the polymers according to the invention do not have processing problems of conventional functionalized diene polymers exhibiting high affinity for white fillers.

    本发明涉及用于轮胎的弹性体胶料用组合物,组合物包括用含至少一种2,5二取代四唑的至少一个四唑基团(E)封端的改性二烯聚合物(A1),其可通过加热来活化,包含它们的用于车辆车轮的轮胎部件和轮胎。有利地,本发明的改性二烯聚合物(A1)赋予胶料较低的热滞后和降低的佩恩效应,因此较低的滚动阻力和磨耗。此外,本发明聚合物没有显示出对白色填料具有高亲和性的常规官能化二烯聚合物的加工问题。
