中文摘要:
      以三苯基膦氯化铑为催化剂,对丁腈酯橡胶(BNBR)进行均相溶液加氢处理,研究催化剂质量分数和反应温度对氢化丁腈酯橡胶(HBNBR)加氢度的影响,并研究BNBR和HBNBR的耐热性能。结果表明:当催化剂质量分数为0.003 8、反应温度为100 ℃时,HBNBR的加氢度达到99%;与BNBR相比,HBNBR的热稳定性和耐热老化性能大幅提高。
英文摘要:
      Using RhCl(PPh33 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.
