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