制备了不同离子基团含量的端二羟基聚丁二酸丁二醇酯离聚体前体（Pre-PBSI），并与端二羟基聚丁二酸丁二醇酯进行扩链反应，合成了离子基团分布可控的高分子量聚丁二酸丁二醇酯离聚体（PBSI）。采用核磁共振谱和凝胶渗透色谱对前驱体和PBSI的化学结构和分子量进行了表征。通过透射电子显微镜（TEM）、差示扫描量热仪（DSC）、偏光显微镜（POM）、广角X射线衍射仪（WAXD）、旋转流变仪和拉伸试验，研究了离子基团分布对PBSI的形态、热行为、等温结晶动力学、流变行为和力学性能的影响。TEM观察发现，随着预聚体中离子基团含量的增加，预聚体中PBSI和PBS链段发生相分离，DSC和WAXD研究发现，预聚体的结晶得到改善，而复合粘度和拉伸强度则有所下降。这些结果表明，PBSI的性质可以通过离子基团的分布来调节。
Dihydroxyl terminated poly(butylene succinate) ionomer precursors (Pre-PBSIs) with different ionic group contents were prepared to chain-extend with dihydroxyl terminated poly(butylene succinate) to synthesize high molecular weight poly(butylene succinate) ionomers (PBSIs) with controlled ionic group distributions. The chemical structures and molecular weights of the precursors and PBSIs were characterized by nuclear magnetic resonance spectroscopy and gel permeation chromatography. The effect of ionic group distribution on the morphology, thermal behavior, isothermal crystallization kinetics, rheological behavior, and mechanical properties of PBSIs were investigated by transmission electron microscopy (TEM), differential scanning calorimeter (DSC), polarizing optical microscopy (POM), wide angle X-ray diffraction (WAXD), rotational rheometer, and tensile testing. With the increase of ionic group content in incorporated Pre-PBSI, phase separation between PBSI and PBS segments occurred as observed by TEM, the crystallization was improved as investigated by DSC and WAXD, while the complex viscosity and tensile strength decreased as studied by rotational rheometer and tensile testing. All the results indicated that the properties of PBSI can be regulated by the ionic group distribution.
