Zusammenfassung:	PURPOSE:To provide a premature vulcanization inhibitor fir rubber, consiting of a specified 2,4,6-substd.-1,3,5-S-triazine compd. CONSTITUTION:A 2,4,6,-substd.-1,3,5-S-triazine compd. of formulaI[wherein R is-SSR1,R2; R1 is (cyclo)alkyl, benzyl, trichloromethyl, pheyl, a group of formula II (wherein Y is halogen, alkyl, nitro, carboxyl), naphthyl; R2 is alkylamino, alkoxy, phenoxy, -NH2 etc.] such as 2,4,6-tris (isopropyldithio)-1,3,5-s-triazine, is used as a premature vulcanization inhibitor for rubber. 0.1-5pts.wt. said triazine compd. per 100pts.wt. rubber is used. Scorch time can be retarded by the addition of a small amount of said compd. By adjusting the amount of said compd. to be blended, scorch time or vulcanizing time can be freely controlled.
