Oligomeric organosilicon compounds consisting of ethylene-polysulfane chains in which each ethylene unit is substituted with one triorganosilylalkyl group. Oligomeric organosilicon compounds of formula (I): R<1>-R<3> = H, 1-4C alkyl, alkoxy, haloalkyl or haloalkoxy, phenyl, aryl or aralkyl; Z = 0-6C alkylidene which may be attached to either of the two carbon atoms, with the free valency taken up by hydrogen; x = 1-6; n = 1-150. Independent claims are also included for: (a) a process for the production of (I) by reacting compounds of formula (II) with compounds of formula MSH or M2Sy, or with M2S and sulfur,at 20-150 degrees C and normal pressure or at up to 6 bar, optionally in presence of solvent and/or catalysts; (b) oligomeric organosilicon compounds (I) obtained by this process; (c) rubber mixtures containing (I); (d) a process for the production of rubber mixtures using rubber, other filler(s) and compounds (I); and (e) molded products obtained from these rubber mixtures. X = halogen; M = a metal ion; y = 2-6 (statistical average) The full definitions are given in the DEFINITION (Full Definitions) Field. |
