| Abstract: |
| The hindered phenolic antioxidants with rare earth （lanthanum，cerium，praseodymium，neodymium，samarium and europium） were characterized by IR spectrometry and thermogravimetry analysis method，and the influence of the antioxidant type on the curing behavior，physical properties and aging resistance of the NR compound was investigated.The results showed that，NR compounds with the rare earth type hindered phenolic antioxidants had similar curing behavior，the physical properties and aging resistance of the vulcanizates were improved，and the lanthanum hindered phenolic antioxidant showed the best result. |
