A diene rubber comprised of a conjugated diene homopolymer or a conjugated diene/aromatic vinyl copolymer; the homopolymer or copolymer having at least one end of its polymer chain a quaternary ammonium group to which four carbon atoms have been bound, and containing 0 to 60% of aromatic vinyl units; at least 10% of the bound conjugated diene units being a vinyl bond; and the homopolymer or copolymer further having a weight average molecular weight (Mw) of 100,000 to 2,000,000. This rubber exhibits well reduced heat build-up, which is an index of a well reduced rolling resistance, and having tensile strength and abrasion resistance.
一种二烯橡胶,由共轭二烯均聚物或共轭二烯/芳香族乙烯基共聚物组成;均聚物或共聚物的聚合物链至少一端有一个与四个碳原子结合的季铵基团,并含有 0 至 60% 的芳香族乙烯基单元;结合的共轭二烯单元中至少有 10% 是乙烯基键;均聚物或共聚物的重量平均分子量(Mw)为 100,000 至 2,000,000 。这种橡胶能很好地减少热量积聚(这是很好地减少滚动阻力的指标),并具有拉伸强度和耐磨性。
