Silane, rubber mixture containing the silane, and vehicle tire having the rubber mixture in at least one component

Abstract

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):(R)Si—R—X-A-Y—[R—Y—]—R—S—R—[—Y—R]—Y-A-X—R—Si(R),wherein according to the invention it has spacer groups between the respective silyl groups and the Smoiety, which have an aromatic group A and at least one alkylene group Rand 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—, —RNC(═O)NR—, —RNC(═NR)NR—, —RNC(═S)NR—, wherein at least one Rwithin 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—, —RNC(═O)NR—, —RNC(═NR)NR—, —RNC(═S)NR—, wherein at least one Rwithin each group Y is a hydrogen atom, and wherein the radicals Rwithin 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.
