【摘要】 聚氯乙烯（PVC）因机械性能优异、加工性好，被广泛应用于电缆、建材、人造革与包装领域。但是由于其刚性较大，通常需依赖增塑剂赋予柔韧性。系统概述了聚酯增塑剂对PVC性能调控的研究进展，重点探讨了结构设计、合成方法及其应用效果，通过对比分析分子结构、支化结构及端基功能化策略，阐明了聚酯增塑剂对PVC热稳定性、力学性能、迁移行为及加工流变性的影响机制。结果表明，合理设计聚酯分子结构可显著提升增塑效率与相容性，并降低增塑剂迁移与挥发的风险。生物基单体来源与绿色合成技术是聚酯增塑剂发展的关键方向，未来应聚焦多功能协同设计与规模化制备，以推动其在医疗、电缆与包装等领域的应用，实现高性能环保型PVC材料的可持续发展。更多还原

【Abstract】 Polyvinyl chloride(PVC) is widely used in cables, building materials, artificial leather and packaging fields due to its excellent mechanical properties and good processability. However, because of its high rigidity, it needs to rely on plasticizers to endow flexibility. This paper systematically summarizes the research progress on the performance regulation of PVC by polyester plasticizers, with a focus on the structural design, synthesis methods and their application effects. Through comparative analysis of different molecular structures, branching structures and end group functionalization strategies, the influence mechanisms of polyester plasticizers on the thermal stability, mechanical properties, migration behavior and processing rheology of PVC are summarized. The results show that the rational design of the molecular structure of polyester can significantly improve the plasticizing efficiency and compatibility, and reduce the risk of plasticizer migration and volatilization. The conclusion holds that the source of bio-based monomers and green synthesis technology are the key directions for the development of polyester plasticizers. In the future, efforts should be focused on multi-functional collaborative design and large-scale preparation to promote their application in fields such as medical care, cables, and packaging, and achieve the sustainable development of high-performance and environmentally friendly PVC materials.更多还原
