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—[R7—Y—]m—R7—Sk—R7—[—Y—R7]m—Y-A-X—R2—Si(R1)o,
wherein according to the invention it has spacer groups between the respective silyl groups and the Sk moiety, which have an aromatic group A and at least one alkylene group R7 and also 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, and wherein the radicals R7 within a molecule may be identical or different and comprise alkylene radicals having 1 to 20 carbon atoms, which may have cyclic, branched and/or aliphatically unsaturated groups.
The inventive rubber mixture comprises at least one inventive silane.
