用差示扫描量热法对聚对苯二甲酸乙二酯（ＰＥＴ）／热致液晶高分子（ＬＣＰ）共混体系的等温和非等温结晶行为进行了研究．结果表明，由于液晶组分的加入，共混体系中ＰＥＴ的结晶速率和结晶度均得到提高．说明ＬＣＰ具有ＰＥＴ结晶成核剂的作用．在较低的ＬＣＰ组分含量下（～２ｗｔ％），这一效果最为明显，说明ＬＣＰ是以很小的微区或某些ＬＣＰ分子链介晶微束的形式对ＰＥＴ的结晶起成核剂的作用．
The isothermal and non-isothermal crystallization behaviors of polyethylene terephthalate (PET) / thermotropic liquid crystal polymer (LCP) blends were investigated by differential scanning calorimetry. The results showed that the crystallization rate and crystallinity of PET in the blends increased due to the addition of liquid crystal components. Explain that LCP has the function of PET crystallization nucleating agent. This effect is most pronounced at lower LCP content (~ 2 wt%), indicating that LCP nucleates PET nuclei in the form of very small domains or some LCP molecular chain mesogenic microbeams Role.
