橡胶混合物及车辆轮胎
摘要：
本发明涉及一种橡胶混合物，特别是用于车辆轮胎，该混合物的特征在于改善的滚动阻力行为以及改善的磨损特性，并且涉及一种车辆轮胎。为此目的，该橡胶混合物含有至少以下组分：‑5至100phr的至少一种根据以下式I)的聚合物A：I)F‑(P‑Y‑P‑Sx)z‑P‑Y‑P‑F，其中S是硫原子，P是弹性聚合物链，该链在二引发剂的存在下通过至少一种共轭二烯以及任选地至少一种乙烯基芳香族化合物的阴离子聚合获得，Y是衍生自该二引发剂的双碳负离子基团，x对于每一个Sx基团独立地是大于或等于1的整数，条件是x对于至少一个Sx基团是选自数2、3和4，z是从1至160的整数，并且每个F彼此独立地为选自下组的端基，该组由以下各项组成：‑H、‑SH、‑SOH、‑SCl、‑SSCl、‑SO2H和‑SO3H，以及至少一种填充剂。
摘要（英）：

A rubber mixture for vehicle tires which exhibits improved rolling resistance behavior and improved wear properties. The rubber mixture includes: 5 to 100 phr of at least one polymer A of the formula I): 1) F-(P-Y-P-Sx)z-P-Y-P-F, wherein S is sulfur, P is an elastomer polymer chain obtained by the anionic polymerization of a conjugated diene and, optionally, a vinyl aromatic compound in the presence of a diinitiator, Y is a dicarbanion group derived from the diinitiator, x is an integer greater than or equal to 1 independently for each Sx group, on the condition that x is selected from the numbers 2, 3, and 4 for at least one Sx group, z is an integer from 1 to 160, each F is a terminal group independently selected from —H, —SH, —SOH, —SCl, —SO2H and —SO3H, and at least one filler.
