摘　　要：采用直接酯化缩聚路线合成了具有较高特性黏度、含成核剂的聚对苯二甲酸丙二醇酯(PTT)材料。研究了反应温度、反应时间、单体配比、催化剂种类及用量等因素对PTT合成过程的影响,并讨论了成核剂的加入对PTT缩聚过程的影响。By using the direct esterification polycondensation method synthesized polytrimethylene terephthalate with higher characteristic viscosity and nucleating agent. Has studied the effect of PTT synthesizing process on reaction temperature, reaction time, monomer allocated proportion, the type and amount of catalyst and so on factors, and discussed the influence of the PTT condensation process by adding the nucleating agent.
