中国作为全球聚氯乙烯（PVC）第一生产与应用大国，其产能产量约占全球45%，且PVC是维持氯碱工业氯平衡的关键产品。然而，PVC固有的热稳定性不足和循环利用困难严重制约了其可持续发展。本文针对PVC分子链中不稳定氯原子（结构缺陷）导致的热稳定性差这一问题，提出一种基于分子结构修饰与可逆交联协同提升PVC性能的策略，选取三种呋喃基化合物通过化学反应替换PVC分子链上不稳定的氯原子，从分子层面消除热降解主要引发点，改善其热稳定性；通过合成双马型钙锌热稳定剂与引入的呋喃环发生热可逆Diels-Alder反应，在PVC内部形成可逆共价交联网络，实现PVC材料的可逆共价交联增强和可修复循环利用，协同实现PVC制品的高性能化与功能化，为其可持续发展提供新途径。本论文主要研究内容与结果如下：
（1）通过一锅法成功实现了糠醇、糠酸与PVC之间的亲核取代反应，糠醛与PVC之间的瑞福马斯基反应；通过红外，拉曼，核磁表征，证明成功制备了接枝改性PVC材料（Fa-g-PVC、Fm-g-PVC和FF-g-PVC）。三种改性PVC材料经刚果红测试，静态热稳定时间分别延长8.08 min、7.59 min和5.74 min，延迟了PVC脱HCl的时间；热解第一阶段因呋喃甲氧基/呋喃甲羧基/呋喃甲羟基取代不稳定氯后主链稳定性增强，PVC主链的脱HCl反应被抑制（Cl含量减少）最大失重率降低；通过热降解动力学参数计算，Fa-g-PVC和Fm-g-PVC热降解第一阶段脱HCl反应活化能提高，热稳定性得到提升。
（2）基于生物基呋喃（二烯体）与马来酸酐（亲双烯体）的热可逆D-A动态反应，成功合成了双马型钙锌热稳定剂，通过单因素试验法得出糠醛与PVC反应的最优条件，与自制双马型钙锌热稳定剂和FF-g-PVC形成自修复体系。通过元素分析、熔点测定、红外光谱确定了产物的合成，通过改变钙锌热稳定剂不同质量确定最佳配比；通过红外和核磁氢谱表征自修复前后的分子结构，证实了D-A动态交联网络的可逆形成；通过SEM观察到自修复后的PVC也由脆性断裂转变为延性断裂；热重分析表明其热稳定性获得提升；对合成的PVC样板进行力学性能测试，经热处理一次后的样品拉伸强度修复率为56.81%，实现了PVC材料的自修复。
 

As the world’s leading producer and consumer of polyvinyl chloride (PVC), China accounts for approximately 45% of global production capacity and output. PVC serves as a crucial product for maintaining chlorine balance in the chlor-alkali industry. However, its inherent thermal instability and recycling challenges severely constrain sustainable development. This study addresses the poor thermal stability caused by labile chlorine atoms (structural defects) in PVC molecular chains. We propose a synergistic strategy combining molecular structural modification with reversible cross-linking to enhance PVC performance. Three furan-based compounds were selected to substitute unstable chlorine atoms on PVC chains through chemical reactions, eliminating primary thermal degradation initiation sites at the molecular level and improving thermal stability. Simultaneously, a bismaleimide calcium-zinc thermal stabilizer was synthesized to undergo thermally reversible Diels-Alder reactions with the introduced furan rings. This forms reversible covalent cross-linking networks within PVC, enabling reinforcement and repairable recyclability. The synergistic approach achieves both high-performance functionalization of PVC products and provides a novel pathway toward sustainable development. The main research contents and results of this thesis are as follows:
(1) The nucleophilic substitution reactions between furfural, furfonic acid and PVC, as well as the Rovema-Smak reaction between furfural and PVC were successfully achieved using the one-pot method. Through infrared, Raman and nuclear magnetic resonance characterization, it was proved that the graft-modified PVC materials (Fa-g-PVC, Fm-g-PVC and FF-g-PVC) were successfully prepared. After being tested with Congo red, the static thermal stability times of the three modified PVC materials were extended by 8.08 min, 7.59 min and 5.74 min respectively, delaying the time of PVC losing HCl; in the first stage of thermal decomposition, due to the instability of the chlorine after the substitution of furan methoxy/furan monocarboxylate/furan methoxy group on the main chain, the stability of the PVC main chain was enhanced, and the HCl removal reaction of the main chain was inhibited (the content of Cl decreased) and the maximum weight loss rate decreased; through the calculation of thermal degradation kinetic parameters, the activation energy of the HCl removal reaction in the first stage of thermal degradation of Fa-g-PVC and Fm-g-PVC increased, and the thermal stability was improved.
(2) Based on the thermally reversible D-A dynamic reaction of bio-based furan (diene) and maleic anhydride (dienophile), a bis-maleimide calcium-zinc heat stabilizer was successfully synthesized. The optimal conditions for the reaction between furfural and PVC were obtained through single-factor experiment method, and a self-repairing system was formed with the self-maleimide calcium-zinc heat stabilizer and FF-g-PVC. The synthesis of the product was determined by elemental analysis, melting point determination and infrared spectroscopy. The optimal ratio was determined by changing the mass of calcium-zinc heat stabilizer; the molecular structure before and after self-repair was characterized by infrared and nuclear magnetic resonance hydrogen spectra, confirming the reversible formation of D-A dynamic crosslinking network; SEM observation showed that the PVC after self-repair also changed from brittle fracture to ductile fracture; Thermogravimetric analysis indicates that its thermal stability has been enhanced; mechanical properties of the PVC sample after thermal treatment once were tested, and the repair rate of tensile strength was 56.81% after one-time thermal treatment, achieving the self-repair of PVC materials.
