中文摘要:
      采用热重-差示热重分析和差热分析研究了环氧化天然橡胶(ENR)/PVC共混物的热氧降解过程。结果表明，炭黑补强的ENR/PVC共混物的热氧降解过程分为3个阶段，第1阶段主要是PVC脱氯化氢，而氯化氢引起ENR发生催化氧化反应而放热，且该阶段明显受到ENR/PVC共混比的影响，随着PVC用量的增大，共混物的热氧稳定性下降。
英文摘要:
      The thermo-oxidative degradation of ENR/PVC blend was investigated by TG-DTG and DTA.The results showed that the degradation process of ENR/PVC blend filled with carbon black consisted of three steps；the exothermic HCl-catalysed oxidative reaction of ENRwas resulted from giving-off of HCl during the first step；and the first step of degradation process was affected by the blending ratio of ENR/PVC，the thermo-oxidative aging property decreased as the proportion of PVC increased.
