植物油增塑剂的使用可以为增塑聚氯乙烯(PVC)材料开辟新的应用领域。本研究合成了新型环保型蓖麻油型多元醇酯(COPE-1、ECOPE-1、COPE-2和ECOPE-2)，并用FT-IR和H-1NMR对其进行了表征。研究了聚氯乙烯材料的性能，并与商品增塑剂(DOP和ESO)进行了比较。结果表明，蓖麻油多元醇酯能显著提高聚氯乙烯共混物的热稳定性。COPE-2和ECOPE-2对PVC的增塑效果优于DOP、ESO、COPE-1和ECOPE-1。迁移稳定性和挥发稳定性试验表明，随着蓖麻油多元醇酯相对分子质量的增加，其迁移稳定性和挥发稳定性增强。它们是主要的增塑剂，在食品包装、儿童玩具、医疗器械等领域具有潜在的应用前景。
The use of vegetable oil based plasticizers can create new application for plasticized poly(vinyl chloride) (PVC) materials. In this study, novel environmental castor oil based polyol esters (COPE-1, ECOPE-1, COPE-2 and ECOPE-2) were synthesized and characterized with FT-IR and H-1 NMR PVC materials were prepared via blending the synthesized castor oil based polyol esters as the main plasticizer. Properties of the PVC materials were investigated and compared to those of commercial plasticizers (DOP and ESO). The results showed that castor oil based polyol esters could significantly improve thermal stability of PVC blends. Plasticizing effect of COPE-2 and ECOPE-2 on PVC was better than that of DOP, ESO, COPE-1 and ECOPE-1. Migration stability and volatility stability of tests showed that with the increasing of the molecular weight of castor oil based polyol esters, the migration stability and volatility stability are enhanced. They could be with potential application used in food packing, children toys and medical devices as the main plasticizer.
