Novel modified Polyacrylic acid (ACTP) bearing triazole pendant moieties prepared with polyacrylyl chloride and 3-amino-1,2,4-triazole-5-thiol through polycondensation reaction. The synthesized polymer was characterized using nuclear magnetic resonance (^lH-NMR, ¹³C-NMR), fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), energy dispersive studies (EDAX) and thermogravimetric (TGA) studies. The ACTP polymer was tested as corrosion inhibitor with aluminium metal in alkaline medium and their results were compared with synthesized simple polyacrylic acid (PAA). Gravimetric, electrochemical impedance spectroscopy (EIS), potentiodynamic polarization techniques were used to test the efficiency of the corrosion inhibitor. Activation energy and free energy for inhibition reaction supports both chemical and physical adsorption mechanism, with better inhibition efficiency. Potentiodynamic polarization curves validated that the corrosion inhibitors behave an anodic type.

新型改性的带有三唑侧基的改性聚丙烯酸（ACTP），其通过缩聚反应与聚丙烯酰氯和3-氨基-1,2,4-三唑-5-硫醇制备。使用核磁共振对合成的聚合物进行表征（¹ H-NMR，¹³C-NMR），傅立叶变换红外光谱（FTIR），扫描电子显微镜（SEM），能量色散研究（EDAX）和热重分析（TGA）研究。测试了ACTP聚合物与铝金属在碱性介质中作为缓蚀剂的性能，并将其结果与合成的简单聚丙烯酸（PAA）进行了比较。重力，电化学阻抗谱（EIS），电位动力学极化技术用于测试缓蚀剂的效率。抑制反应的活化能和自由能同时支持化学和物理吸附机理，抑制效率更高。电位动力学极化曲线验证了缓蚀剂表现为阳极型。
