| 摘 要： | 聚对苯二甲酸丙二醇酯（PTT）是一种具有广泛应用前景的新型聚酯纤维,兼有聚对苯二甲酸乙二酯（PET）、聚对苯二甲酸丁二酯（PBT）、聚酰胺（PA）的优良性能,其蓬松性、回弹性、柔韧性、抗污性、耐磨性、抗潮性、染色性等使用性能和加工性能较好.合成PTT,以Ti及其化合物为催化剂,采用直接酯化法路线为佳,酯化时所需反应温度高于PET,缩聚温度低于PET,各阶段反应时间比PET短.根据我国国情,开发研究1,3-丙二醇（1,3-PD）、PTT具有极其重要的战略意义.

| Abstract: | Poly trimethylene terephthalate（PTT）is a prospect of wide application of new polyester fiber,having excellent performance of PET,PBT and PA,its fluffy and elasticity,flexibility,fouling,and wear resistance,anti-wave,and the dyeing properties such as the use of performance and processing performance are better.Synthesis of PTT,used to Ti and its compounds as a catalyst,and PTA synthetic route is better,the esterification reaction temperature is higher than required for PET,polycondensation temperature is lower than PET,the various stages of the reaction time is shorter than the PET.According to China＇s national conditions,it should make the best use of 1,3-Propanediol（1,3-PD）,PTT＇s research and development,will have an extremely important strategic significance. |
