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), ¹H nuclear magnetic resonance (NMR), and ¹³C 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 °C, the initial decomposition temperature (T_i), 10% and 50% mass loss temperatures (T₁₀ and T₅₀), had maximum increases of 8.0, 20.0, and 27.5 °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.

桐油基三缩水甘油酯增塑剂的合成及其对聚氯乙烯软膜的影响

制备了桐油衍生的可再生增塑剂，马来酸三缩水甘油酯（TMTE），并首次将其掺入聚氯乙烯（PVC）中。通过傅里叶变换红外（FTIR），¹ H核磁共振（NMR）和¹³1 H NMR。研究了TMTE代替邻苯二甲酸二辛酯（DOP）在软质PVC薄膜中的塑化效果。通过热重分析（TGA），TGA-FTIR，TGA-质谱，动态力学分析和力学测试，研究了纯PVC和PVC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膜具有更高的热稳定性，增塑效果，相容性和柔韧性。当将30 phr（每100份树脂的份数）DOP用TMTE代替PVC混合物时，玻璃化转变温度（T _g）从41.46降至40.18°C，即初始分解温度（T _i）），10％和50％的质量损失温度（T ₁₀和T ₅₀）分别最大增加了8.0、20.0和27.5°C。还讨论了TMTE与PVC分子之间的相互作用。此外，对增塑剂的提取，渗出和耐挥发性进行了分析，并通过溶解度参数进行了分析，结果表明，随着TMTE含量的增加，PVC膜的迁移稳定性得到了提高。
