用马来酸酐（TMA）氨解乙二胺（ED）和对苯二胺（PPD），分别制备了N-（2-氨基乙基）马来酸（AETMA）和N-（2-氨基苯基）马来酸（APTMA）。然后通过一步法分别合成了LAETMA-Ca、LAPTMA-Ca、LABTMA-Zn和LAPTMA-Zn，并用傅里叶变换红外光谱（FTIR）、1H核磁共振（NMR）和电感耦合等离子体原子发射光谱（ICP-AES）对其进行了表征。以LAETMA-Ca/LAETMA-Zn和LAPTMA-Ca/LAPTMA-Zn作为聚氯乙烯（PVC）的热稳定剂，采用刚果红试验、热老化试验、紫外可见光谱法、热重分析（TGA）、热红外光谱法（TGA）和热质谱法（MS）对其进行了研究。并与其他常用稳定剂进行了稳定效果比较。对聚氯乙烯复合材料的动态力学性能进行了研究。与其他稳定剂相比，LAPTMA-Ca/LAPTMA-Zn具有良好的长期稳定性和较好的PVC增塑性能，可以部分替代对苯二甲酸二酯（2-乙基己基）在PVC加工中的应用。提出了LAPTMA-Ca/LAPTMA-Zn稳定作用的机理。
N-(2-amino ethyl) tung maleamic acid (AETMA) and N-(2-amino phenyl) tung maleamic acid (APTMA) were prepared from the ammonolysis of ethidene diamine (ED) and p-phenylenediamine (PPD) respectively with tung-maleic anhydride (TMA). Then LAETMA-Ca, LAPTMA-Ca, LABTMA-Zn and LAPTMA-Zn were separately synthesized through a one-step method and characterized by Fourier transform infrared spectrometry (FTIR),1H nuclear magnetic resonance (NMR) and inductively coupled plasma atomic emission spectroscopy (ICP-AES). LAETMA-Ca/LAETMA-Zn and LAPTMA-Ca/LAPTMA-Zn were both used as thermal stabilizers of polyvinyl chloride (PVC) and investigated using Congo red test, thermal aging test, ultraviolet-visible spectrometry, thermogravimetric analysis (TGA), TGA-FTIR, and TGA–mass spectrometry (MS). Their stabilizing efficiencies were compared with other common stabilizers. Dynamic mechanical of the PVC compounds were also studied. The LAPTMA-Ca/LAPTMA-Zn exhibits excellent long-term stability and better plasticization performance for PVC than other stabilizers, and thus can partly replace di(2-ethylhexyl) terephthalate in the processing of PVC. The mechanism underlying the stabilizing action of LAPTMA-Ca/LAPTMA-Zn is suggested.
