| 摘 要： | 本文合成并应用熔体纺丝法得到了(AKABKB)n型聚酰胺酯一聚醚弹性纤维。用X光衍射及差示扫描量热法研究了它的组成、拉伸、热历史等因素对其结晶行为的影响。并计算了有限长分子链体系内共聚物与均聚物比例及KA、KB。将计算值与实验结果进行了比较并结合体系内相分离情况对实验现象进行了讨论分析了双重结晶峰的成因。

| Abstract: | A series of new type of elastic fibers formed of poly(ester amides) and poly(tetramethy lene ether)glycol segments are made from the melt- spinning.The influence of composition,stress and annealling on the crystallizaion is investigated by x-Ray diffraction and differential ther- mal analysis.The results especially the formation of two crystallization- peaks are discused in view of the phase seperation and the sequence distribution statistics for finite chain length. |
