| Abstract: |
| The application of liquid antioxidant（antioxidant for short） B7081l in neodymium butadiene rubber（NdBR） was studied，and compared with antioxidant B7802，1520 and B7720. The results showed that，compared the compound of NdBR with three other antioxidant，the compound of NdBR with antioxidant B7081L exhibited good Mooney viscosity stability and yellowing resistance，the gel content after thermal oxidative aging did not change significantly，and the oxidation induction time was larger. |
