聚对苯二甲酸丁二烯酯（PBT）是一种新加入的工程热塑性聚酯材料。其良好的平衡性能，如机械强度，可塑性和快速结晶使其广受欢迎(1)。这就产生了研究其结构和性质的需要。一系列芳香族和脂肪族聚酯的结构。Pratt和Hobbs(4)使用去偏振光强和差示扫描量热法（DSC）技术对聚对苯二甲酸乙酯、聚对苯二甲酸丁二烯和聚丙烯的结晶动力学进行了比较研究。Hobbs和Pratt(5)也报道了一些关于PBT皮肤核心形态学研究的结果。最近Misra和Stein(6)对PBT进行了详细而系统的研究。他们的大部分工作是关于熔体结晶的。据报道，PBT表现出两种类型的上层结构，这取决于样品的热历史。然而，PBT从无定形玻璃态结晶后仍保持透明，但没有给出细节(6)。在本文中，我们报道了PBT从非晶玻璃态结晶后的一些性质。
Poly (buty1ene terephthalate)(PBT) is a recent addition to the engineering thermoplastic polyester materials. Its well-balanced properties such as mechanical strength, moldability, and rapid crystallization have made it popular (1). This gives rise to the need to study its structure and properties. anism for a series of aromatic and aliphatic polyesters. Pratt and Hobbs (4) have conducted a comparative study of crystallization kinetics for poly (ethy1-ene terephthalate), poly (buty1ene terephthalate), and polypropylene using depolarized light intensity and differential scanning calorimetry (DSC) techniques. Hobbs and Pratt (5) have also reported some results on skin-core morphological studies on PBT. Recently, Misra and Stein (6) have conducted detailed and systematic studies on PBT. Most of their work was on melt crystallization. It was reported that PBT showed two types of superstructures that depended on the thermal history of the sample. However, PBT remained transparent when crystallized from amorphous glassy state but no details were given (6). In this communication we report some properties of PBT when crystallized from its amorphous glassy state.
