摘要：

Compounds (LSR) with reactive substituted thio groups (-SR) attached to the leaving groups (-L) are generally effective inhibitors of cure. Such compounds include thioimides, sulfenamides, thioketals and polysulfides. In this report the Hammett analysis is extended to the phthalimides, BtSSR, 2-benzothiazole sulfenamide accelerators (with the aid of **1**3C NMR), and N,N prime -dithiobisformanilide vulcanizing agents. The validity of the calculated sigma * values of the substituted phenylthio group is also demonstrated.
