Resumen
The polyacetylene was investigated by us showing the presence of conductive states in the Fermi level caused by a disordered distribution of defects of soliton type. Also we have shown that the polyazine polymer presents conductive characteristics through defects of the bipolaron type for orderly and disordered systems. The aim of this investigation is to verify whether the copolymer from polyacetylene and polyazine can be found on the metallic regime. For the calculations of this system we used semiempirical methods for the optimization of the geometry. Our results indicate that, when we take of charge from the structure, the bipolaron type of defect is formed on the copolymer. 101 1 365 366 Lavarda, F.C., Dos Santos, M.C., Galvão, D.S., (1994) B.Laks,Phys.
