Electrochemical polymerization of 2-aminothiazole

Electrochemical polymerization of 2-aminothiazole (AT) was studied in acetonitrile with tetrabutylammonium tetrafluoroborate (TBAFB) as the supporting electrolyte via constant potential electrolysis (CPE). The redox behavior of AT was investigated in the same solvent-electrolyte couple by cyclic voltammetry, CV. CPE of AT produced a soluble conducting polymer on the electrode surface. The effects of temperature, monomer concentration and polymerization time on the rate of electrochemical polymerization were also studied. The structural analyses of the polymer were carried out by H-1-NMR, FTIR and UV-VIS spectroscopies and elemental analysis. Thermal properties were studied by DSC and TGA. Conductivity measurements were carried out by four-probe technique and the number average molecular weight, M (n), of the polymer was determined by cryoscopy.
