| abstract |
The present invention relates to new oligomeric organosilicon compounds of the general formula I (see above formula) wherein R1, R2, R3 independently of one another denote H, (C1 - C4)alkyl, (C1 - C4)alkoxy, (C1-C4) haloalkoxy, (C1 - C4) haloalkyl, phenyl, aryl or aralkyl and Z denotes an alkylidene radical having 0 - 6 carbon atoms, x can be a statistical average of 1 - 6 and n = 1 - 150 and . . . means that Z can be bonded either to the one or the other C atom, and the particular free valency is occupied by a hydrogen. and their use in rubber mixtures and for the production of shaped articles, in particular pneumatic tyres. |
