摘要
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。
The PAB (P-aminbenzoic acid)/PET (polyethlene trephthalate) thermostropic liquid crystal copolyestramides were studied by WAXD and DSC,The results show that the crystallite sizes of copolymers greatly increase deu to PAB mesophase units in copolymer chains,but the crystallographic interplanner spacing is invariable and the crystallinity of copolyesteramides decreases on a large scale.
