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 containing the silane and to a vehicle tire comprising the rubber mixture in at least one component. The silane according to the invention has the following formula I)(R)Si—R—X-A-Y—[R—Y—]—R—S-G,  I)wherein according to the invention it has a spacer group between the silyl group and the S-G moiety, wherein the spacer group has an aromatic group A and at least one further aromatic group and/or an alkylene group and also the linking units X and Y, wherein the group X is 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 the group X is a hydrogen atom, and wherein the groups Y 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 Rare selected from aromatic groups A and alkylene radicals having 1 to 20 carbon atoms, which may have cyclic, branched and/or aliphatically unsaturated groups; and wherein G is a hydrogen atom or a —C(═O)—Rgroup or a —SiRgroup, wherein Ris selected from linear, branched and cyclic C-C-alkyl groups, C-C-aryl groups, C-C-alkenyl groups and C-C-aralkyl groups, and wherein m can take the values 0 to 4. The rubber mixture according to the invention contains at least one silane according to the invention.
