摘　　要：采用DSC方法研究了PA13N在不同降温速率下的结晶过程，并利用Avrami方程研究了其非等温结晶动力学。在非等温结晶过程中，随着降温速率的增大，结晶温度向低温偏移。综合利用Avrami方程得到Avrami指数为1．35～1．88和结晶速率常数Zj≈1；并求得其结晶活化能为-58．42kJ／mol。结果表明，PA13N的结晶能力小于其他脂肪族尼龙。The non-isothermal crystallization processes and kinetics of poly（tridecame thylene2,6- naphthalamide） （PA13N） were studied by DSC. The Avrami equation can be used in the primary stage of non-isothermal crystallization kinetics. For the non-isothermal crystallization, the peak temperature of the DSC curves gradually decreases with cooling rate increasing. According to Avrami equatiorl, the ratio of Avrami index was calculated as 1.3-1.88, the crystallization rate constant 1, the activation energy-58.42kJ/mol. The results showed that PAl3 was harder to be crystallized as compared with other aliphatic nylon.
