The present paper was treats to the thermal study of the poly-vinylphenyl dithiocarbamats triethylammonium (PVPDT) and their respective monomers. The PVPDT was prepared is polyaminostyrene by chemicals reactions, synthetic procedures for the preparation were described. The chemical structures of the polymers were characterized by FT-IR spectroscopy and elemental analysis. The physical properties of polymers including solution viscosity, thermal stability and thermal behaviour were studied as well. The polymer showed excellent stability. Their inherent viscosities were in the range of 0,7 – 1.0 dL/g. Thermal study of the polymers show that at the first stage of the thermolysis process, there is an elimination of the triethylamine and the carbon disulfide. The kinetic parameters of the elimination process have been evaluated using the theoretical Horowitz-Metzger method. At the second stage, the obtained monomer undergoes a polymerization according to a Zwitter-ion mechanism.
