摘　　要：将0.5份(0.1g)的硫醇甲基锡与1.5份(0.3g)的硬脂酸钡复配使用,发现两者提高了聚氯乙烯的热稳定性。当升温速率β=5℃/min、分解率α=5%时,其热分解温度超过了208℃,表现出较好的热稳定效果与协同效应。The effects of the complexion of methyl tin mercaptide and barium stearate on the poly （vinyl chloride） were studied, the result indicated that they improved the thermal stability of PVC. The decomposition temperature was greater than 208℃ when the heating rate is 5℃/min and the decomposition rate is 5%. It showed good thermal stability and synergistic effect.
