Abstract: Bis(2,4-organylthio-s-triazine-6-yl) polysulfides of the general Formula (I) ##STR1## prepared from compounds of the general formula (II) ##STR2## and from an ammonium or alkali polysulfide and the use of such compounds as accelerators in vulcanizable rubber mixtures.

Abstract: Mixtures of sulfurous triazine compounds and methods of preparing these compounds with the general formula ##STR1## in which R.sup.1, R.sup.2 =H,R.sup.2 =benzyl,R.sup.2, R.sup.3, R.sup.4 =C.sub.1 -C.sub.8 -alkyl, allyl, C.sub.3 -C.sub.8 cycloalkyl, the latter unsubstituted or substituted with 1-3 methyl groups, 2-hydroxyethyl, 3-hydroxypropyl, 2-hydroxypropyl orR.sup.3 and R.sup.4 (together): C.sub.4 -C.sub.6 -alkylene, --(CH.sub.2 --CHX).sub.2 Y withX=H, CH.sub.3, Y=O,S,S.sub.a : Polysulfide chain with 2-10 S atoms (i.e. 2.ltoreq.a.ltoreq.10), in which the individual polysulfides are present in such concentrations that the statistical average value of "a" is a whole or fractional numerical value in the range from 2 to 5., characterized in that a triazine compound of the general formula ##STR2## in which R.sup.1, R.sup.2, R.sup.3, R.sup.
