| 摘 要： | 通过WAXD，POM对聚对苯二甲酸丙二醇酯（PTT）与聚对苯二甲酸丁二醇酯（PBT）共混物．在非等温条件下结晶度及晶貌形态进行了研究。结果表明，PTT／PBT共混体系的结晶度随着组分含量变化而变化。当PTT，PBT的组分相差很大时，其结晶性能好；当PTT，PBT的组分接近时．其结晶性能差。等温结晶时问及组分含量对晶体的生长有一定的影响。

| Abstract: | The crystallization properties and crystal morphologies of the PTT/PBT blends were studied by WAXD and POM under non-isothermal conditions. The results show that the crystallinity of the blends varies with the contents of the components. Crystallizing properties are better when the difference between the contents of PBT and PTT is larger; and are worse when the contents are close to each other. The time of isothermal crystallization has effect on the morphologies of the crystals. A longer time is beneficial to the growth of the crystal. |
