以桐油为原料合成了一种可再生增塑剂--马来酸三缩水甘油酯（TMTE），并首次将其用于聚氯乙烯（PVC）中。通过傅里叶变换红外光谱（FTIR）、H-1核磁共振（NMR）和C-13 NMR研究了其化学结构。研究了TMTE取代邻苯二甲酸二辛酯（DOP）对软质PVC薄膜的增塑作用。采用热重分析（TGA）、TGA-FTIR、TGA-质谱、动态力学分析、力学性能测试等方法研究了纯PVC和PVC薄膜的热稳定性、热降解性能、动态力学性能和力学性能。结果表明，用TMTE增塑的PVC膜具有提高的热稳定性、增塑效果、相容性和柔韧性。当PVC共混物中用TMTE取代30 phr（每百份树脂的份数）DOP时，玻璃化转变温度（T-g）从41.46降至40.18摄氏度，初始分解温度（T-i）、10%和50%质量损失温度（T-10和T-50）分别最大增加8.0、20.0和27.5摄氏度。并对TMTE与PVC分子间的相互作用进行了讨论。通过溶解度参数分析了增塑剂的萃取、渗出和抗挥发性能，结果表明，随着TMTE用量的增加，PVC膜的迁移稳定性提高。
A tung-oil-derived renewable plasticizer, tung-maleic triglycidyl esters (TMTE), was prepared and incorporated into poly(vinyl chloride) (PVC) for the first time. The chemical structure was studied by Fourier transform infrared (FTIR), H-1 nuclear magnetic resonance (NMR), and C-13 NMR. The plasticizing effects of TMTE replacement of dioctyl phthalate (DOP) in soft PVC films were researched. Thermal stability, thermal degradation performance, dynamic mechanical property, and mechanical properties of pure PVC and PVC films were investigated with thermogravimetric analysis (TGA), TGA-FTIR, TGA-mass spectrometry, dynamic mechanical analysis, and mechanical test. The results showed that PVC films plasticized with the TMTE exhibited increased thermal stability, plasticizing effect, compatibility, and flexibility. When 30 phr (parts per hundred parts of resin) DOP was substituted with TMTE in PVC blends, glass transition temperature (T-g) dropped from 41.46 to 40.18 degrees C, the initial decomposition temperature (T-i), 10% and 50% mass loss temperatures (T-10 and T-50), had maximum increases of 8.0, 20.0, and 27.5 degrees C, respectively. The interaction between TMTE and PVC molecule was also discussed. Furthermore, the extraction, exudation, and volatility resistance of plasticizers were carried out and analyzed by solubility parameters, the results of which revealed the migration stabilities of PVC films were promoted with the increasing amount of TMTE.
