摘　　要：以对苯二甲酸二甲酯和 1 ,3-丙二醇为原料合成聚对苯二甲酸丙二酯 (PTT) ,重点研究了原料配比、缩聚温度、催化剂用量、稳定剂用量对聚合物粘度和端羧基含量的影响规律。结果表明 ,温度对聚合物性能影响最大 ,其它 3个因素的影响较小。Dimethyl terephthalate (DMT) and 1,3\|propanediol were selected as raw material to synthesize polytrimethylene terephthalate (PTT). The effects of polymerization parameters including the molar ratio of monomers, polycondensation temperature, the amount of catalyst and stabilizer on the properties of PTT such as intrinsic viscosity and carboxyl end group content were emphatically investigated. The result showed that the temperature has a profound effect on polymer property while the other three factors have a little.
