邻苯二甲酸酯可以被其他无害和环保的增塑剂所取代，例如异山梨醇二酯（ISB）和环氧化向日葵籽油（ESO），后者已被证明是聚氯乙烯（PVC）的有效稳定剂，有助于防止加工过程中的降解。实现了基于具有不同量的ISB、ESO和邻苯二甲酸二（2-乙基己基）酯（DEHP）的PVC的制剂，所述不同量的ISB、ESO和邻苯二甲酸二（2-乙基己基）酯（DEHP）为0至60重量份/100份树脂。为了使PVC具有柔韧性，部分量的邻苯二甲酸酯作为增塑剂，我们使用DEHP，ISB和ESO的组合。这两种生物基增塑剂，ISB和ESO，以及它们与DEHP的混合物的热稳定性，通过测量变色度和热重分析，对机械性能，如拉伸强度，断裂伸长率和硬度的影响，其特征在于。研究了PVC胶料的增塑剂耐久性。研究表明，通过添加增塑剂系统（ISB、ESO和DEHP），可改善加工性和柔韧性。ISB和/或ESO含量的增加提高了热性能和机械性能，而具有ISB/ESO/DEHP（15/15/30）三元组成的组合物表现出最佳的性能。(c)2014年塑料工程师学会
Phthalates can be replaced by other harmless and environmentally friendly plasticizers, such as isosorbide diesters (ISB), and epoxidized sunflower oil (ESO), which has been proved an efficient stabilizer for poly (vinyl chloride) (PVC) in helping to prevent degradation during processing. Formulations based on PVC with different amounts of ISB, ESO, and di-(2-ethylhexyl) phthalate (DEHP) from 0 to 60 parts by weight per hundred parts of resin were realized. To make PVC flexible with partial amounts of the debated phthalates as plasticizers, we use a combination of DEHP, ISB, and ESO. Effects of these two biobased plasticizers, ISB and ESO, and their mixture with DEHP on thermal stability by measuring discoloration degrees and thermal gravimetric analysis, on mechanical properties such tensile strength, elongation at break, and hardness, were characterized. Plasticizer permanence properties of PVC compounds were studied. Studies showed that processibility and flexibility were improved by the addition of a plasticizer system (ISB, ESO, and DEHP). An increase in the content of ISB and/or ESO increased thermal and mechanical properties, whereas compositions with ternary compositions of ISB/ESO/DEHP (15/15/30) exhibited the best performance properties.
