Patent ID: 7662874

Claim:
A rubber mixture, comprising (A) at least one styrene-butadiene rubber, (B) at least one filler, (C) more than one polysulphidic organo(alkyl polyether silane) compound of the general formula I where X is an alkyl polyether group —O—((CR II 2 ) w —O—) t -Alk having from 14 to 29 carbon atoms, t=from 2 to 9, w=from 2 to 9, R II is, each independently of the other, H, a phenyl group or an alkyl group, Alk is a branched or unbranched, saturated or unsaturated, aliphatic, aromatic or mixed aliphatic/aromatic monovalent C 10 -C 25 -hydrocarbon group, X′ is branched or unbranched alkyl, branched or unbranched alkoxy, a branched or unbranched C 2 -C 25 alkenyloxy group, a C 6 -C 35 aryloxy group, a branched or unbranched C 7 -C 35 alkylaryloxy group, a branched or unbranched C 7 -C 35 aralkyloxy group, or an X, X″ is branched or unbranched alkyl, branched or unbranched alkoxy, a C 2 -C 25 alkenyloxy group, a C 6 -C 35 aryloxy group, a branched or unbranched C 7 -C 35 alkylaryloxy group, a branched or unbranched C 7 -C 35 aralkyloxy group, or an X, R I is a branched or unbranched, saturated or unsaturated, substituted or unsubstituted, aliphatic, aromatic or mixed aliphatic/aromatic divalent C 1 -C 30 hydrocarbon group, m is from 1 to 12, wherein the alkyl polyether groups of the polysulphidic organo(alkyl polyether silane) compounds are variously ethoxylated, (D) a thiuram sulphide accelerator and/or carbamate accelerator and/or the corresponding zinc salts, (E) a nitrogen-containing co-activator, (F) optionally additional rubber auxiliaries, and (G) optionally additional accelerators.
