VIBRO-STIMULATOR DEVICE PROCESS FOR THE PREPARATION OF SULPHIDIC DERIVATIVES OF TRIAZIN AND ITS DEPROPORTION PRODUCTS USED IN VULCANIZABLE RUBBER COMPOSITES AND PROCESS FOR OBTAINING RESISTANT RUBBER COMPOSITES AND RETICTIVE PROTECTION

摘要

Compounds of the general formula IMAGE in which R1, R2 denote H; R2 denotes benzyl, R2, R3, R4 denote C1-C8-alkyl, allyl, C3-C8-cycloalkyl, the latter being unsubstituted or substituted by 1-3 methyl groups, 2-hydroxyethyl, 3-hydroxypropyl, 2-hydroxypropyl or R3 and R4 (together) denote C4-C6-alkylene, -(CH2-CHX)2Y where X is H, CH3 and Y is O, S and their oligosulphide disproportionation products, whose average statistical chain length corresponds to S4 are prepared from the corresponding N,N'-substituted diaminomercaptotriazines. The substances according to the invention are used in vulcanisable rubber mixtures as crosslinking agents without sulphur or as vulcanisation accelerators together with sulphur.
