| 中文摘要: |
| 采用刚果红法研究硬脂酸盐热稳定剂对氯化聚乙烯（CPE）脱氯化氢热降解性的影响。结果表明，随着硬脂酸盐用量增大，CPE的脱氯化氢温度呈升高趋势，脱氯化氢初始时间呈延长趋势；采用硬脂酸铅和硬脂酸钡的CPE脱氯化氢温度较高，脱氯化氢初始时间较长；硬脂酸铅/硬脂酸钡、硬脂酸铅/硬脂酸钙和硬脂酸钙/硬脂酸钡并用比分别为1∶1，2∶1和1∶3时，CPE的脱氯化氢温度较高，并用比分别为3∶1，2∶1和1∶1时，CPE的脱氯化氢初始时间较长。 |

| The effect of the stearate stabilizers on the dehydrochlorination of CPE was investigated by Congo Red Method.The results showed that the dehydrochlorination temperature of CPE tended to increase and the initial dehydrochlorination time tended to extend as the stearate level increased；the dehydrochlorination temperature was higher by using lead stearate and barium stearate and its initial time was longer；and the dehydrochlorination temperature of CPE was higher by using lead stearate/barium stearate，lead stearate/calcium stearate，or calcium stearate/barium stearate with blending ratios of 1：1，2：1 and 1：3 respectively，and the initial dehydrochlorination time was longer when the above blending ratios changed to 3：1，2：1 and 1：1 respectively. |
