摘　　要：根据热失重曲线和运用Ｘ射线衍射（ＸＲＤ）所测得的实验结果，讨论了聚糠醇（ＰＦＡ）和聚糠酮（ＰＦＫ）两种呋喃树脂在氮气气氛中热解过程中的结构变化。结果表明，两种试样在４５０℃以前，随着炭化温度的升高，聚合物分子的原有序态结构逐渐被破坏；４５０℃以后，随着炭化温度的升高。Structural conversions of PFA and PFK resins have been studied by thermogravimetric curves and using XRD when pyrolytic carbonization of them in nitrogen atmosphere. The analytical results shew that the original polymeric chain structure of them have been spoilt gradually with the rising carbonized temperature before 450 and the new network lameller structures with six-membered rings have been formed and increased gradually with the rising carbonized temperature after 450 .
