A series of polyester-based ionomers containing dimethyl 5-sulfoisophthalate sodium salt (DMSI) with up to 5 mol-% diacid units was synthesized by two-step polycondensation. Furthermore a polylactic acid (PLA) was modified by introducing poly(ethylene-co-methacrylic acid) ionomers with different ion groups, such as Na, Li, and Zn, using the melt blending method. This review examines the effect of the ionic group on the dynamic mechanical properties, melt rheology, crystallization behavior, degradation behavior, and biocompatibility with human dermal cells, as well as the nucleating effect of poly(ethylene-co-methacrylic acid) ionomer in PLA.
通过两步缩聚反应合成了一系列含有高达5摩尔%二酸单元的5-磺基间苯二甲酸钠盐（DMSI）的聚酯基离聚物。此外，采用熔融共混法，通过引入具有不同离子基团（如Na、Li和Zn）的聚（乙烯-共-甲基丙烯酸）离聚物对聚乳酸（PLA）进行了改性。本综述研究了离子基团对动态力学性能、熔体流变学、结晶行为、降解行为以及与人类真皮细胞的生物相容性的影响，以及聚（乙烯-共-甲基丙烯酸）离聚物在聚乳酸中的成核作用。
