Mixtures of sulfurous triazine compounds and methods of preparing these compounds with the general formula <IMAGE> I in which R1, R2=H,R2=benzyl, R2, R3, R4=C1-C8-alkyl, allyl, C3-C8 cycloalkyl, the latter unsubstituted or substituted with 1-3 methyl groups, 2-hydroxyethyl, 3-hydroxypropyl, 2-hydroxypropyl or R3 and R4 (together): C4-C6-alkylene, -(CH2-CHX)2 Y with X=H, CH3, Y=O,S, Sa: Polysulfide chain with 2-10 S atoms (i.e. 2</=a</=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 <IMAGE> I in which R1, R2, R3, R4 have the meanings indicated above is reacted with an ammonium polysulfide or alkali polysulfide and dissolved in a protic polar solvent, especially water, at a temperature of 80 DEG to 140 DEG C. |
