摘　　要：通过广角Ｘ射线衍射（ＷＡＸＤ）研究了聚２，６－萘二甲酸乙二醇酯（ＰＥＮ）在不同温度与时间下的结晶行为。结果表明，ＰＥＮ的结晶能力比ＰＥＴ差，磷酸酯的添加对ＰＥＮ有异相成核的作用，添加了热稳定剂的ＰＥＮ比未添加热稳定剂的ＰＥＮ的高温结晶完善性好。在所研究范围内，ＰＥＮ只存在一种结晶相，未出现晶相转变。Crystallization behavior of poly(ethylene naphthalene)(PEN) under different temperature and time was studied by means of WAXD. The results show that crystallization ability of PEN is not so good as PET because additive phosphate makes PEN out of phase crystallization. High temperature crystallization property of PEN with additive thermal stabilizer is better than that of PEN without additive thermal stabilizer. In the studying range, there is only one crystal modification, no crystal modification changeover.
