摘　　要：通过小型实验进行PTA直接酯化法合成聚醚酯热塑性弹性体的工艺研究。以精对苯二甲酸、1,4-丁二醇、聚四氢呋喃为主要原料,以钛酸四丁酯为主要催化剂,添加抗氧剂、紫外线吸收剂等助剂合成聚醚酯热塑性弹性体,确定其合成的最佳工艺条件。The technology research of synthesis of polyether ester thermoplastic elastomer with PTA direct esterification method by lab experiment was carried out. The purified terephthalic acid,1,4-butanediol,poly tetrahydrofuran was used as the main raw material,with tetrabutyl titanate as main catalyst,adding antioxidant,ultraviolet absorber to synthetize polyether ester thermoplastic elastomer（ TPEE）. The appropriate conditions for synthetize TPEE were determined.
