Mixture of organosilanepolysulphanes and a process for the production of rubber compounds containing these mixtures.

摘要

THIS INVENTION RELATES TO MIXTURES OF ORGANOSILANEPOLYSULPHANES OF THE GENERAL FORMULA (RO)3SI(CHZ)X S-SZ - S (CHZ)X SI(OR)3 (I) IN WHICH R MEANS ALKYL; LINEAR OR BRANCHED, HAVING 1-8 C ATOMS, IN PARTICULAR 1-3 C ATOMS X MEANS AN INTEGER FROM 1-8 Z MEANS 0 TO 6, WHEREIN SUM OF THE PROPORTIONS OF POLYSULPHANES IN WHICH Z = 0 AND Z = 1 AMOUNTS TO  80% (BY WEIGHT), PROVIDING THAT THE PROPORTION OF COMPOUNDS IN WHICH Z = 0 REMAINS BELOW 80% AND THE PROPORTION OF ORGANOSILANEPOLYSULPHANES IN WHICH Z MEANS AN INTEGER FROM 2 TO 6 DOES NOT EXCEED A PROPORTION OF 20 WT.% IN THE MIXTURES, AND TO THE RUBBER COMPOUNDS PRODUCED USING THESE MIXTURES, IN PARTICULAR FOR TYRE TREADS.
