| Abstract: |
| Using RhCl（PPh3）3 as catalyst，butadiene-acrylonitrile-butylacrylate rubber（BNBR） was hydrogenated in homogenous solution.The effects of catalyst concentration and reaction temperature on the hydrogenation degree of hydrogenated BNBR（HBNBR），and the heat resistance of BNBR and HBNBR were investigated.The results showed that，when the mass fraction of catalyst was 0.003 8 and reaction temperature was about 100 ℃，the hydrogenation degree reached 99%.Compared with BNBR，the thermal stability and heat resistance of HBNBR increased sharply. |
