| 摘 要： | 采用ＳＡＸＳ和ＷＡＸＳ技术，对不同温度热处理的ＰＢＴ－ＰＥＧ无规多嵌段共聚醚酯的相变化进行研究．结果表明，随着热处理温度的提高，结晶区体积增大，且主要是侧向增长，同时无定形区的体积也增加，两相间过渡层变薄，趋于形成理想的两相结构．

| Abstract: | The annealing induced morphological changes in random block copoly (ether-ester)s are investigated by SAXS and WAXD. The copolymer is based on polybutylene terephthalate and poly ethylene glycol. Results indicate that the volume of crystallits increases, which is mainly due to the lateral growth of the lamellae, with increasing the annealing temperatures. Meanwhile, the volume of amorphous domains increases, diffuse boundary zone existing between two phases becomes thin and the structure tends to be ideal two phase model. |
