Oligomeric organosilanepolysulfanes which are built up from the three structural units A and/or B and/or C,in which Y=H, CN, -(CH2)nSiRR1R2;n=1-8,R, R1, R2 and R3, independently, represent H, (C1-C4)alkyl, (C1-C4)alkoxy, halogen or a OSiR1R2R3 group;x, as a statistical average, is 1-6,z, as a statistical average, is 2-6,n is 1-8 ando, p and q are each a whole, positive number between 1 and 40 where o+p+q may be >=2 and <40, with the proviso that at least one structural unit A or B is present,and their use in rubber mixtures and to produce molded items, in particular pneumatic tires. |
