  • Rubber mixtures
    Patent number: 6548594
    Abstract: Rubber mixtures which comprise (a) a rubber or a mixture of rubbers, (b) a silicatic filler, (c) an organosilane of the general formula (I) R1R2R3Si—R4—SH  (I) (d) an alkylsilane of the general formula (II) R1R2R3Si—R5  (II). They are prepared by mixing the rubber or the mixture of rubbers, the silanes according to the formulae I and II and the silicatic filler in a mixing unit and adding the silanes according to the formulae I and II together or separately in succession. They can be used in shaped articles.
