Conducting polymers (CP) have attracted considerable interest since the invention of doped polyacetylene in 1977. Since then, a large variety of conjugated polymers have been developed, such as polythiophenes, polyanilines and polypyrroles. CP show almost no conductivity (uncharged) state. Their intrinsic conductivity results for the formation of charge carriers upon oxidizing (p-doping) or reducing (n-doping) their conjugated backbone. Oxidation of the neutral polymer and following relaxation processes causes the generation of localized electronic states and a so-called polaron is formed. Due to the interest in the development of new conductive polymers, we are working in the synthesis, characterization of poly-3-amine-1,2-4-trizole (PAT). The 3-amine-1,2-4-triazole (3AT) is a monomer water soluble and easily polymerized when is treated with ammonium persulphated in neutral  media. The polymer is precipitated in basic media. The new polymer was characterized by physical, spectroscopical and thermal methods. The PAT is no conductive material, however, our preliminary results show that polymer powders protonated with camphorsulfonic acid (CSA) exhibit semiconductor behaviour (10-5S/cm). These results are similar to PANI. We will show the synthetic pathway, the characterization and the conductivity evaluation. An example of that is the thermal analysis -which is shown in Figure 1- where we can see the different thermal behaviour between the monomer and the polymer
