Abstract:
Rubber compounds comprising one or more soluble rubbers, 5 to 500 phr of hydrophobized filler having a methanol wettability of 1 to 60 weight percent, and 0.1 to 40 phr of one or more polysulfidic-silane compounds on an inorganic or organic support wherein said polysulfidic-silane compounds on an inorganic or organic support are those prepared by the reaction of (haloalkyl)silanes (I) and, if required, organic halogen compounds (II) with polysulfides (III) in water at temperatures in the range of 20-220.degree. C. in the presence of an organic or inorganic support, the mole ratios of the components (I):(II):(III) depending on the number of bound halogen atoms in such a way that there are from 1.5 to 3 halogen atoms to every molecule of polysulfide, and the mass ratio of the polysulfidic-silane compound to support being from 0.1 to 10.
