| 中文摘要: |
| 试验研究动态硫化NBR/石油发酵尼龙（PFPA）热塑性弹性体的热性能。结果表明，随着PFPA用量的增大，动态硫化NBR/PFPA热塑性弹性体的玻璃化温度升高，熔点降低，熔融焓减小，热稳定性提高；动态硫化NBR/PFPA热塑性弹性体的热降解过程分2个阶段进行，且2个阶段均为一级反应。 |
| 英文摘要: |
| The thermal properties of dynamically-vulcanized NBR/petroleum fermented polyamide(PFPA) TPE were experimentally investigated.The results showed that as the proportion of PFPA increased，the Tg of dynamically-vulcanized NBR/PFPA TPE raised，the melt point lowered，the melting enthalpy decreased and the thermal stability improved；and the thermal degradation process of dynamically-vulcanized NBR/PFPA TPE was devided into two steps and the both steps were involved in the first order reactions. |
