Provided are a rubber mixture, a method for preparing the rubber mixture to reduce the discharge of an alcohol during mixing process and to improve the elongation at break, and its use for preparing a molded product. A rubber mixture comprises at least one styrene-butadiene rubber; at least one filler; and at least one polysulfidic organo(alkyl polyether silane) represented by [(X)(X')(X'')Si-R^I]2-Sm, wherein X is a C14-C29 alkyl polyether group; X' is a linear or branched alkyl, alkoxy, C2-C25alkenyloxy, C6-C35 aryloxy, C7-C35 alkylaryloxy or C7-C35 aralkyloxy group, or X; X'' is a linear or branched alkyl, alkoxy, C2-C25alkenyloxy, C6-C35 aryloxy, C7-C35 alkylaryloxy or C7-C35 aralkyloxy group, or X; R^I is a linear or branched saturated or unsaturated aliphatic, aromatic or aliphatic/aromatic divalent C1-C30 hydrocarbon group; and m is 1-12.
