A triazine type compound and thiadiazoles prepared in Part I and mixed type compounds of a mercapto-thiadiazolecoupled with a moiety of the commercial accelerators and thiolsulfonate type compounds prepared in Part II were utilized as vulcanization accelerator for natural rubber. By using each one of them as accelerator, and compounding Hakuenka or carbon black as well as the other ingredients, vulcanizates were obtained under a given condition and their physical properties were compared with those of vulcanizates with commercial accelerator, D, M or TT. Accelerated aging test of vulcanizates with new accelerators was also carried out. On the basis of the results obtained here new accelerators were found to have comparable efficiency to the commercial accelerators.
