| Abstract: |
| The reversion of NR cured with semi-EV system was studied.The effects of 3 commercial anti-reversion agents，i.e.Si69，N，N′-m-phenylene bismaleimide (HVA-2)and cyclohexane dithiosulfate dihydrate(HTS) on the anti-reversion of NR were investigated by determing curing curves，physical properties and swelling indexes.The results showed that the antireversion agents could improve the thermo-oxygen aging properties of NR and the order of their effects was Si69>HVA-2>HTS；and 3 phr of anti-reversion agent was suitable. |
