摘要：

We have prepared 10 new derivatives of 2-mino-4,6-dimercapto-1,3,5-triazine and 2,4-diamino-6-mercapto-1,3,5-triazine. The compounds have a very high antioxidant activity in cast films of natural rubber. They also have a favourable effect on the retention of viscosity after ageing and on the destruction index. Their grafting capacity was appreciable, measured by the extractable sulphur content and the protection of the vulcanizates after acetone extraction. Their extraordinary efficiency is due to the internal synergism, and their grafting capacity is due to the presence of -SH or -SR groups.
