Poly(butylene adipate-co-terephthalate) (PBAT) has been functionalized with Pluronic F127 as a secondary diol monomer by melt polycondensation. The variation of Pluronic content to max 12.2 wt% in the copolymer is investigated on microstructure analysis, molecular weight distribution, thermal properties, crystallinity, and thermo-responsive behavior. The microstructure in the Pluronic F127-functionalized PBAT (PPBAT) copolymer indicates that the amount of Pluronic unit which is attached to the PPBAT copolymers found to be increased from 5.9 to 9.1 to 12.2% (wt) with the feeding amount of 1.0 to 2.0 to 3.0 mmol, respectively. The weight average molecular weight has also found to increase from 23,555 to 43,841 g/mol in the PPBAT copolymers. The lowering of glass transition temperature has been also observed in the thermal analysis that indicates the improvement of the plasticization effect in the PPBAT copolymers with the increase of Pluronic from 0 to 12.2% (wt). Moreover, the crystallization behavior also indicates the disappearance of crystallization temperature and the appearance of cold crystallization temperature before melting with the increase of Pluronic content. The X-ray diffraction analysis further signifies the decrease in degree of crystallinity with an increase of Pluronic in PPBAT copolymers. The PPBAT copolymers display thermo-responsive behavior under physiological conditions due to the attachment of Pluronic comonomer onto the structural backbone.

聚（丁烯己二酸酯共-对苯二甲酸酯（PBAT）已通过熔融缩聚反应以Pluronic F127作为仲二醇单体进行了功能化。通过微观结构分析，分子量分布，热性能，结晶度和热响应行为，研究了共聚物中Pluronic含量最大为12.2 wt％的变化。Pluronic F127官能化的PBAT（PPBAT）共聚物的微观结构表明，与PPBAT共聚物连接的Pluronic单元的数量从9.0增至9.1到12.2％（wt），进料量为1.0到2.0至分别为3.0mmol。在PPBAT共聚物中，还发现重均分子量从23,555增加到43,841g / mol。在热分析中还观察到玻璃化转变温度的降低，这表明随着Pluronic从0％增至12.2％（wt），PPBAT共聚物的增塑效果得到改善。而且，随着Pluronic含量的增加，结晶行为还表明结晶温度的消失和熔融前冷结晶温度的出现。X射线衍射分析进一步表明，随着PPBAT共聚物中Pluronic的增加，结晶度降低。由于Pluronic共聚单体附着在结构骨架上，PPBAT共聚物在生理条件下显示出热响应行为。随着Pluronic含量的增加，结晶行为也表明结晶温度的消失和熔化前冷结晶温度的出现。X射线衍射分析进一步表明，随着PPBAT共聚物中Pluronic的增加，结晶度降低。由于Pluronic共聚单体附着在结构骨架上，PPBAT共聚物在生理条件下显示出热响应行为。随着Pluronic含量的增加，结晶行为也表明结晶温度的消失和熔化前冷结晶温度的出现。X射线衍射分析进一步表明，随着PPBAT共聚物中Pluronic的增加，结晶度降低。由于Pluronic共聚单体附着在结构骨架上，PPBAT共聚物在生理条件下显示出热响应行为。
