Abstract: The invention relates to rubber mixtures which comprise at least one rubber, at least one mercaptosilane of the general formula I R13Si—R2—S—R3 and at least one mixture of polysulfanes of the formula II R13Si—R2SxR2—SiR13. The rubber mixture is produced by mixing at least one rubber, at least one mercaptosilane of the general formula I and at least one mixture of polysulfanes of the formula II. The rubber mixture can be used to produce moulded articles.

Abstract: The invention relates to rubber mixtures, said rubber mixtures comprising (a) at least one rubber, excluding silicone rubber, chloroprene rubber, bromobutyl rubber, fluoro rubber and nitrile rubber, (b) at least one silane of general formula (I), G-Si(—OR)3??(I), (c) at least one amine compound selected from the list triethanolamine, triisopropanolamine and [HO—CH(phenyl)CH2]3N and (d) at least one bifunctional silane. The rubber mixture is produced by mixing the rubber, silane of general formula (I), amine compound and bifunctional silane.

Abstract: The invention relates to rubber mixtures, wherein these comprise at least one rubber, excluding silicone rubber, and at least one silatrane of general formula (I) G-Si(—O—CX1X2—CX1X3—)3N??(I) The rubber mixture is produced by mixing at least one rubber and a silatrane of formula (I). The silatrane of formula (I) may be used as a secondary accelerator in rubber mixtures.

Abstract: A composition containing 2-ethylhexyl silicate, is produced by heating a reaction mixture of ethyl silicate with an excess amount of 2-ethylhexanol in the presence of titanium tetrabutoxide as catalyst to a temperature below the boiling point of 2-ethylhexanol while mixing, allowing the reaction mixture to react and, after the reaction, removing ethanol and excess 2-ethylhexanol from the reaction mixture by distillation and obtaining the composition containing 2-ethylhexyl silicate.

Abstract: Azocarbonyl-functionalized silanes of formula I (R1)3-a(R2)aSi—R1—NH—C(O)—N?N—R4??(I) and methods for their production are provided. The silanes of formula (I) are useful in rubber mixtures to provide moldings having improved tear-resistance.

Abstract: A silicon-containing azodicarboxamide is obtainable by reacting an azodicarboxy compound with an aminosilane. The silicon-containing azodicarboxamides are suitable for use in cable sheathing, hoses, drive belts, conveyor belts, roll coverings, footwear soles, ring seals and damping elements.
