摘　　要：用自制高压装置，对聚酰胺－６（ＰＡ６）在常压至１．２ＧＰａ压力下熔体的结晶行为进行了研究。通过差示扫描量热（ＤＳＣ）、宽角Ｘ射线衍射（ＷＡＸＤ）以及扫描电子显微镜（ＳＥＭ）分析发现，在特定高压条件下，生成了含伸直链晶体、结构规整的ＰＡ６材料。A study has been made on the crystallization of polyamide 6 from the melt under high pressure.The morphology and structure has been investigated by means of differential scanning calorimetry,wide angle X ray diffraction and scanning electron microscopy.The experimental facts show that during the crystallization of polyamide 6 under high pressure,the size of the crystal as well as the crystalline order have increased considerably,and extended chain crystal has been grown.
