| 摘 要： | 采用差示扫描量热仪研究了原位增容聚酰胺6/高密度聚乙烯（PA6/PE-HD）共混物的等温结晶行为，采用Avrami方程分析了纯PA6和PA6/PE-HD共混物的等温结晶动力学，并通过Hoffman-Weeks方法计算出了共混物的平衡熔点。结果表明，二者的Avrami指数介于2.19~3.70之间，表明PA6晶体的生长方式为二维盘状生长和三维球晶生长并存，PE-HD的加入并没有影响PA6晶体的生长方式。偏光显微镜分析表明，纯PA6能够生成球晶，但加入PE-HD后，球晶尺寸明显变小，说明PE-HD的加入起到了异相成核的作用，加快了PA6的结晶过程。

| Abstract: | The isothermal crystallization behavior of in-situ compatibilized polyamide 6/high density polyethylene(PA6/PE-HD) blends was studied using differential scanning calorimetry.The isothermal crystallization kinetics was analyzed using Avrami equation.The calculated Avrami index n was between 2.19 and 3.70,which demonstrated that the crystallization of PA6/PE-HD blends was growing three-dimensionally,which was confirmed by polarized optical microscopy observation.The equilibrium melting temperatures of PA6/PE-... |
