摘要: 以聚酰胺6(PA6)作为第二组分对聚芳醚腈(PEN)进行了改性,通过熔融共混制备了PEN/ PA6共混体系。用扫描电镜、差示扫描量热分析仪、X-射线衍射等方法对共混体系的形态结构和结晶行为进行了研究;用同步分析仪、万能电子试验机对共混材料的耐热性能和力学性能进行了研究。结果表明,PEN与PA6两者具有较好的相容性,随着PA6含量的增加共混体系中PA6的结晶能力逐渐提高,同时由于PA6的加入使得共混体系的加工性能较纯PEN有所改善,共混体系的拉伸强度较纯PEN提高了34 %。

Abstract: Poly(acylene ether nitriles) (PEN)/polyamide6(PA6) blends were prepared via melt mixing. The structures and crystallization behavior of the blends were characterized using SEM, DSC, and XRD. The mechanical and thermal properties were determined using EUTM and STA. It was found that PEN and PA6 were fairly compatible. Upon adding PA6, the processablity of PEN was improved. The tensile strength of the blends was 34 % higher than neat PEN.
