本文采用广角Ｘ 射线衍射仪，示差扫描热分析仪对ＰＡＢ（ 对氨基苯甲胺）／ＰＥＴ（ 聚对苯二甲酸乙二脂） 热致液晶共聚酯酰胺进行了研究，着重探讨了聚合物链组成对共聚物晶态结构和结晶性能的影响。结果表明，随着ＰＡＢ 含量的增加，ＰＡＢ各晶面间距ｄｈｋ１ 基本不变，但结晶晶体结构发生明显畸变，微晶尺寸显著增大，结晶度急剧降低。
In this paper, PAB (para-aminobenzyl) / PET (polyethylene terephthalate) thermotropic liquid crystal copolyesteramides were investigated by wide-angle X-ray diffractometry and differential scanning calorimetry. Effect of Chain Composition on the Crystalline Structure and Crystallization Properties of Copolymers. The results showed that with the increase of PAB content, the dhk1 of the PAB crystal planes remained almost unchanged, but the crystal structure of the PAB was obviously distorted. The crystallite size increased sharply and the crystallinity decreased sharply.
