A vulcanizate of a rubber mixture for a vehicle tire, the rubber mixture containing at least one filler and 10 to 100 phr of at least one polymer A of the following formula:PS&#x2014;R&#x2014;S&#x2014;R)where S is a sulfur atom, and P is a polymer chain which is obtainable by anionic polymerization of at least one conjugated diene and optionally one or more vinylaromatic compounds and which has optionally been chain end-modified, Ris most preferably C-C-alkyl, Ris preferably selected from H and &#x2014;SiRRRin which R, Rand Rare independently selected from H, C-C-alkyl, C-C-aryl and C-C-aralkyl, and n is an integer selected from 1 to 200, where the &#x2014;S&#x2014;R&#x2014;S&#x2014;Rgroup(s) are bonded to the backbone of the polymer chain P.

RUBBER MIXTURE, VULCANIZATE OF THE RUBBER MIXTURE, AND VEHICLE TIRES

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-S)-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 Sgroup, 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 &#x2014;H, &#x2014;SH, &#x2014;SOH, &#x2014;SCl, &#x2014;SOH and &#x2014;SOH, and at least one filler.
