The chemical oxidative polymerization of 2-aminothiazole (AT) was studied in aqueous solution using copper chloride (CuCl2) as an oxidant. The effect of varying the reaction temperature, reaction time and oxidant/monomer molar ratio on the polymer yield was investigated. The resulting poly(2-aminothiazole)s (PATs) were characterized by FTIR, 1H NMR, UV-vis, gel permeation chromatography, scanning electron microscopy, thermogravimetric analysis and four-point probe electrical conductivity measurements. Compared with a previous study, PATs with higher yield (81%) and better thermal stability could be synthesized. The chemical oxidative polymerization kinetics of AT were studied for the first time. The orders of the polymerization reaction with respect to monomer concentration and oxidant concentration were found to be 1.14 and 0.97, respectively, and the apparent activation energy of the polymerization reaction was determined to be 21.57 kJ/mol.

2-氨基噻唑在水溶液中的化学氧化聚合：合成，表征和动力学研究

以氯化铜（CuCl2）为氧化剂，研究了2-氨基噻唑（AT）在水溶液中的化学氧化聚合反应。研究了改变反应温度，反应时间和氧化剂/单体摩尔比对聚合物收率的影响。通过FTIR，1 H NMR，UV-vis，凝胶渗透色谱，扫描电子显微镜，热重分析和四点探针电导率测量对所得的聚（2-氨基噻唑）（PAT）进行表征。与以前的研究相比，可以合成具有更高收率（81％）和更好的热稳定性的PAT。首次研究了AT的化学氧化聚合动力学。相对于单体浓度和氧化剂浓度，聚合反应的阶数分别为1.14和0.97。
