采用两步缩聚的方法合成了一系列二酸含量高达5摩尔%的二甲基5-磺基二苯二甲酸钠（DMSI）基聚酯离聚物。在此基础上，采用熔体共混的方法，引入不同离子基（Na、Li、Zn）的聚乙烯-共甲基丙烯酸离聚体对聚乳酸（PLA）进行了改性。本文综述了离子基对聚乳酸中聚乙烯-甲基丙烯酸离聚体的动态力学性能、熔体流变性、结晶行为、降解行为、与人体真皮细胞的生物相容性以及成核效应的影响。
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.
