摘　　要：采用核磁共振氢谱(^(1)H-NMR)测试了PVC树脂的内部双键数,采用红外光谱测试了PVC树脂的共轭双键相对含量,采用白度法测试了PVC树脂的热稳定性。结果表明:PVC分子中缺陷结构越多,PVC树脂的热稳定性越差,二者之间有较好的对应关系。The internal double bond number of PVC resins were measured by ^(1)H-NMR.The relative content of conjugated double bond of PVC resins were measured by IR.The thermal stability of PVC resins were tested by whiteness method.The results showed that the more defects in PVC molecule,the worse thermal stability of PVC resins,and that there was a close correspondence between them.

关 键 词：PVC 缺陷结构 热稳定性 核磁共振 红外光谱
