The invention relates to a silane, to a rubber mixture comprising the silane and to a vehicle tire comprising the rubber mixture in at least one component.
The inventive silane has the following formula I)
(R1)oSi—R2—X-A-Y-[A-Y-]m-A-Sk-A-[-Y-A]mY-A-X—R2—Si(R1)o,
wherein, according to the invention, the silane has spacer groups between the respective silyl groups and the Sk moiety which have at least two aromatic groups A and the linking units X and Y, wherein the groups X within a molecule may be identical or different from each other and are selected from the groups —HNC(═O)—, —C(═O)NH—, —C(═O)O—, —OC(═O)—, —OC(═O)NH—,
—HNC(═O)O—, —R3NC(═O)NR3—, —R3NC(═NR3)NR3—, —R3NC(═S)NR3—, wherein at least one R3 within each group X is a hydrogen atom; and wherein the groups Y within a molecule may be identical or different from each other and are selected from the groups —HNC(═O)—, —C(═O)NH—, —C(═O)O—, —OC(═O)—, —OC(═O)NH—,
—HNC(═O)O—, —R4NC(═O)NR4—, —R4NC(═NR4)NR4—, —R4NC(═S)NR4—, wherein at least one R4 within each group Y is a hydrogen atom.
The inventive rubber mixture comprises at least one inventive silane.
