| 摘 要： | 利用差示扫描量热仪研究了原位增容的聚酰胺6/高密度聚乙烯（PA6/PE-HD）共混物的非等温结晶过程，用经Jeziorny 修正的Avrami方程和Mo法对其非等温结晶动力学进行了研究，计算并得到非等温结晶动力学参数。结果表明，该方程和方法适合于处理纯PA和PA6/PE-HD共混物的非等温结晶过程；在PA6/PE-HD共混物非等温结晶过程中, 在其初期结晶阶段可能同时包含了均相成核和异相成核, 在二次结晶阶段结晶生长可能是一维生长，并且PE-HD的加入，起到异相成核的作用，促进了晶核的生长。此外, 还利用Vyazovkin的方法求出PA6/PE-HD共混物结晶活化能与温度之间的关系。

| Abstract: | The non-isothermal crystallization kinetics of in-situ compatibilized PA6/PE-HD blends was studied by means of differential scanning calorimetry(DSC).Its non-isothermal crystallization data was analyzed using Jeziorny modified Avrami equation and Mo method.It showed that the above equation and method could well describe the nonisothermal crystallization of PA6 and PA6/PE-HD blends.At primary crystallization stage,there existed both heterogeneous and homogeneous nucleations.In the secondary crystallization s... |
