中文摘要:
      采用热重分析法和导数热重分析法研究低蛋白NR（LPNR）胶乳和NR胶乳在氮气气氛中的热降解性能。结果表明，LPNR胶乳和NR胶乳的热降解过程相似，热降解反应级数相差不大，热降解率均随升温速率增大而略有增大；NR胶乳的平衡起始降解温度较高，LPNR胶乳的平衡最大降解速率温度和平衡终止降解温度与NR胶乳相近；LPNR胶乳的热稳定性比NR胶乳差。
英文摘要:
      The thermal degradation of LPNR latex and NR latex in the nitrogen was investigated by TGA and thermoconductive TGA.The results showed that the thermal degradation process and reaction order of LPNR latex were similar to those of NR latex，and the thermal degradation rate increased a little as the temperature rising increased；the balanced temperature for starting degradation of NR latex was higher，and the balanced temperature for the maximum degradation rate and the balanced temperature for ending degradation of LPNR latex were similar to those of NR latex；and the thermal stability of LPNR latex was poorer than that of NR latex.
