摘　　要：制备了高等规度聚丙烯腈(iso-PAN,mm=0.64),测定了高等规度PAN在空气条件下的TG及DSC。从热失重曲线中发现在预氧化温度(300℃以前),有增重现象。研究了其增重动力学,动力学级数为一。High-tactic polyacrylonitrile（iso-PAN,mm：0. 64）was prepared. TG and DSC curves of iso-PAN were meas ured in atmosphere Investigation of iso-PAN TG curve showed an oxidative gaining weight phenomena. Acorrding to TG and DSC curves, gaining weight phenomena was finded and theoxidative gaining weight kinetics was studied（n= 1; Ea=29. 75 kJ/mol）.
