| Abstract: |
| The oil swellable rubber was prepared with EVM with low VA content and different reinforcing fillers.The influence of addition level of curing agent DCP and fillers on the swelling properties and physical properties was investigated，and the aging properties，performance stability after complete swelling and oil retention were studied.The results showed that，when the addition level of curing agent DCP was 1.5 phr，the physical properties and oil swelling rate of EVM vulcanizates were better.Compared with that filled with silica，the oil swelling property of vulcanizates filled with carbon black was better.The oil swellable EVM rubber showed good aging properties and stability in the acidic，alkaline and salty medium，and possessed higher oil retention. |
