    in which formula R1, R2, R3 and R4 are each a radical of the group consisting of hydrogen, phenyl, alkyl radicals containing up to 18 carbon atoms, alkenyl radicals containing up to 6 carbon atoms, cycloalkyl radicals containing at least 5 and at most 7 carbon atoms, aralkyl radicals containing at least 7 and at most 9 carbon atoms, and the said alkyl, alkenyl, cycloalkyl, phenyl and alkyl radicals that are further substituted with a radical of the group consisting of hydroxyl, cyano and alkoxy radicals containing up to 18 carbon atoms, and X is a radical of the group consisting of

    in which formulae R1, R2, R3 and R4 each have the same significance as hereinbefore and R5 is a radical of the group consisting of phenyl, benzothiazolyl, carbazolyl, phenothiazinyl, alkyl radicals containing up to 18 carbon atoms, and aralkyl radicals containing at least 7 and at most 9 carbon atoms, or a mixture of one or more of the said substituted sym-triazinyl disulfides in an amount between 0.1 and 50 millimols per 100 grams of the elastomer.

    Abstract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

    Abstract: A SUBSTITUTED S-TRIAZINE OF THE FORMULA:

    2-X,4-R'',6-R2-S-TRIAZINE

    WHEREIN X IS HALOGEN, ALKOXY, OR ALKYLMERCAPTO, ALKYL IN ALKOXY AND ALKYLMERCAPTO HAVING 1 TO 6 CARBON ATOMS; R1 IS

    -NH-(CH2)N-C(-R3)(-R4)-(CH2)M-CN

    WHEREIN N AND M ARE ZERO OR 1 WITH THE PROVISION THAT ONLY ONE OF N AND M MAY BE ZERO; R3 AND R4 ARE THE SAME OR DIFFERENT AND ARE STRAIGHT-CHAIN OR BRANCHED-CHAIN ALKYL HAVING FROM 1 TO 4 CARBON ATOMS AND WHEREIN EITHER R3 OR R4 MAY ALSO BE HYDROGEN; AND R2 IS

    -NH-R5

    WHEREIN R5 IS HYDROGEN OR STRAIGHT-CHAIN OR BRANCHEDCHAIN LOWER ALKYL. THE COMPOUNDS ARE USEFUL AS PLANT GROWTH MODIFIERS AND ARE DISTINGUISHED BY A HIGH SELECTIVITY AND A RAPID DECOMPOSITION IN THE GROUND.
