| 中文摘要: |
| 采用刚果红法研究有机锡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，硫醇锡复合热稳定剂T-137和T-395A抑制CPE脱氯化氢的效果优于非硫醇锡热稳定剂二月桂酸二丁基锡；环氧大豆油能协同二月桂酸二丁基锡减慢CPE脱氯化氢速度；热稳定剂用量小于3份时，二月桂酸二丁基锡/二盐基亚磷酸铅和二月桂酸二丁基锡/硬脂酸钡并用体系（并用比1∶1）抑制CPE脱氯化氢的效果较二月桂酸二丁基锡差，热稳定剂用量为3份时则较好。 |

| The effect of various organotin stabilizers on the thermal degradation via dehydrochlorination of CPE was investigated by Congo Red Method.The results showed that the dibutyl tin bis(2-mercaptobenzothiazole) stabilizers T-137 and T-395A were better than dibutyl tin dilaurate in terms of inhibiting the dehydrochlorination of CPE；the better stabilizing effect was also obtained by using 1 phr of dibutyl tin dilaurate combined with 5 phr of epoxidized soybean oil；and the dibutyl tin dilaurate/dibasic lead phosphite or barium stearate blend systems were better than dibutyl tin dilaurate when their addition levels were more than 3 phr respectively. |
