摘要
用ＤＳＣ法研究了两种不同结构热致性液晶共聚酯（ＰＥＴ／６０ＰＨＢ和ＨＴＨ６）分别对ＰＥＴ冷结晶行为的影响．结果表明，随共混体系中ＨＴＨ６含量的增加，ＰＥＴ冷结晶温度逐渐下降，而共混体系中ＰＥＴ／６０ＰＨＢ的加入使ＰＥＴ冷结晶温度突然下降，而后基本不再随ＰＥＴ／６０ＰＨＢ含量的增加而变化．
The crystallization behaviour of the PET glass in the blends of PET/HTH6 and PET/(PET/60 PHB)have been studied by mean of DSC. The cold crystallization temperature of PET in the blends of PET/HTH6 decreases with increasing HTH6 content. In the blends of PET/(PET/60 PHB), the cold crystallization temperatures of PET are much lower than that of pure PET and don't change with increasing PET/60 PHB content. The difference of the crystallization behaviour of the PET in the two kinds of blends have been discussed.
