本文采用Diels-Alder（DA）法和酯化反应合成了松香基增塑剂。首先，松香与马来酸酐的双键通过DA反应得到马来海松酸（RT）。然后在对甲苯磺酸催化下，将RT的羧基和酸酐基与四氢香叶醇酯化，得到松香基多酸酯（RTT）。通过FTIR和1H-NMR检测RT和RTT的结构。以RTT为主增塑剂，制备了增塑聚氯乙烯（PVC）材料，并与DOP进行了比较。结果表明，RTT的加入提高了PVC薄膜的热稳定性，降低了PVC薄膜的Tg。增塑PVC薄膜具有优异的力学性能，弹性模量为-4，793.67 MPa，拉伸强度为-111.86 MPa，高于纯PVC和DOP-6。与DOP相比，RTT在PVC中表现出更好的挥发稳定性、迁移和溶剂萃取。J.乙烯基添加剂一个人，26：180-186，2020.© 2019塑料工程师协会
In this work, rosin‐based plasticizer was synthesized by Diels–Alder (DA) and esterification. First, the maleopimaric acid (RT) was obtained by DA between the double bond of rosin and maleic anhydride. Then, the carboxyl group and anhydride group of RT was esterified with tetrahydro geraniol to obtain the rosin‐based polyacid esters (RTT) under the catalysis of p‐toluene sulfonic acid. The structure of RT and RTT was detected by FTIR and1H‐NMR. RTT was used as main plasticizer to obtain plasticized polyvinyl chloride (PVC) materials and compared with DOP. The results showed that RTT improved the thermal stability and reducedTgof PVC film. Plasticized PVC films had excellent mechanical properties with the elastic modulus of −4,793.67 MPa and tensile strength of −111.86 MPa, higher than that of pure PVC and DOP‐6. RTT showed better volatility stability, migration, and solvent extraction in PVC compared to DOP. J. VINYL ADDIT. TECHNOL., 26:180–186, 2020. © 2019 Society of Plastics Engineers
