    Abstract: The invention relates to a vulcanisation accelerator combination and their use for a process for vulcanising natural and/or synthetic rubber made from halogen-free dienes. As vulcanisation accelerators triazines substituted in the 2, 4 and 6 positions in combination with at least one thiazole accelerator and optionally at least one thiuram accelerator are used. This accelerator combination obviate the disadvantage of the long cure time when using the triazine accelerator alone without loss of the advantage of the high moduli.

The monothiocyanato-s-triazines can be prepared from the corresponding monomercaptotriazines by reaction with cyanogen chloride or cyanogen bromide in the presence of a hydrogen halide acceptor. The bis-thiocyanato-s-triazines can be prepared either by reaction of the corresponding chlorotriazines with potassium, sodium or ammonium thiocyanate in organic solvents, or by reacting the correspondingly substituted dimercaptotriazines with cyanogen chloride or cyanogen bromide in the presence of a hydrogen halide acceptor.

Examples describe the preparation of 3-thiocyanatopropyl triethoxysilane, 3 - triethoxysilyl - propyl. ethyl - xanthogenate, 3 - thiocyanatopropyl tri - n - butoxysilane, and 2 - diethylamino- 4 - mercapto - 6 - (3 - triethoxy - silyl - propyl)- thiotriazine. The above compounds may be used either as vulcanization agents in the crosslinking of elastomers or as a binding agency between inorganic fillers and organic polymers, the required effects occurring in the presence of residual moisture in the mix and in the presence or absence of conventional accelerators or activators. Examples describe the vulcanization of styrene-butadiene and natural rubbers using the above compounds as vulcanizing agents added to the mix or used to pre-treat silica fillers, the vulcanization being carried out in the presence of sulphur and the presence or absence of conventional additives such as zinc oxide, stearic acid, dibenzothiazyl disulphide and diphenyl guanidine.
