  • Vulcanizable rubber formulations with bis(sulfonamido)sulfide
    Patent number: 4053458
    Abstract: Vulcanizable rubber formulations will contain, as an inhibitor therefor, a compound having the formula: ##STR1## in which R and R' are independently selected from the group consisting of alkyl of from 1 to about 6 carbon atoms, cycloalkyl having from 3 to about 8 carbon atoms, phenyl and tolyl radicals. The aforesaid rubber formulations are exemplified by a styrene-butadiene rubber containing bis(N-methyl-p-toluenesulfonamido)sulfide.

  • Vulcanization inhibiting compounds
    Patent number: 4022828
    Abstract: Novel compounds for inhibiting the premature vulcanization of vulcanizable rubber formulations comprising bis-(sulfonamido)-sulfides or polysulfides having the formula: ##STR1## where R and R' are independently selected from the group consisting of aryl, alkyl, cycloalkyl or substituted derivatives thereof and x is an integer of from 1 to 3. These novel compounds may be exemplified by bis-(N-methyl-p-toluenesulfonamido)-disulfide.
