以环氧大豆油（ESO）和磷酸二乙酯为原料，通过开环反应合成了一种新型含阻燃基团的大豆油生物基增塑剂（SOPE）。分别用ESO和SOPE增塑PVC共混物。研究了ESO和SOPE增塑PVC的流变性能、热稳定性、阻燃性能和力学性能。结果表明，增塑PVC共混物具有较好的相容性、热性能和力学性能。作为一种新型的含阻燃基团的生物基增塑剂，热重分析表明，SOPE增塑PVC共混物的热降解温度可达275.5°C。氧指数测试和扫描电镜分析表明，SOPE的加入使PVC共混物的氧指数由24.2%提高到33.6%，SOPE的阻燃作用主要是通过促进聚合物碳化，迅速形成致密的阻燃涂层，有效地阻止热通量和空气侵入。SOPE阻燃性能的提高将扩大其增塑PVC材料的应用范围。© 2015 Wiley Periodicals，Inc.

A novel bio-based plasticizer containing flame retardant groups based on soybean oil (SOPE) was synthesized from epoxidized soybean oil (ESO) and diethyl phosphate through a ring-opening reaction. PVC blends plasticized with ESO and SOPE were prepared, respectively. Properties including rheological behavior, thermal stability, flame retardant performance, mechanical properties of PVC plasticized with ESO and SOPE were carefully studied. The results showed that the plasticized PVC blends indicated better compatibility, thermal, and mechanical properties. As a novel bio-based plasticizer containing flame retardant groups, the TGA data indicated that the thermal degradation temperature of PVC blends plasticized with SOPE could reach to 275.5°C. LOI tests and SEM indicated that the LOI value of PVC blends could increase from 24.2 to 33.6%, the flame retardant performance of SOPE was put into effect by promoting polymer carbonization and forming a consolidated and thick flame retardant coating quickly, which is effective to prohibit the heat flux and air incursion. The enhancement in flame retardancy will expand the application range of PVC materials plasticized with SOPE. © 2015 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015, 132, 42111.
