Abstract

DIAZ, FERNANDO R. et al. SINTESIS, CARACTERIZACION y PROPIEDADES ELECTRICAS DE POLI(p-FENILSULFONIL-ANILINA). Bol. Soc. Chil. Quím. [online]. 2000, vol.45, n.2, pp.181-189. ISSN 0366-1644.  http://dx.doi.org/10.4067/S0366-16442000000200003.

Poly(p-phenylsulfonyl-aniline) have been synthesized by chemical polymerization from the respective monomer using copper perchlorate in CH3CN or potassium dichromate in HCl aqueous media as oxidizing agents. The products were characterized by elemental analysis, FT-IR, 1H-RMN, XPS, SEM and conductivity measurements. The FT-IR spectra of products synthesized in different media were similar. The XPS analysis shows that the polymer synthesized with potassium dichromate have groups sulfone, sulfoxy-hydroxyl and its equivalent radical. Moreover, it have 1% of covalent chlorine, which probably is incorporate by secondary adition reaction. The polymers shows electrical conductivity in the range of semiconduction.

Keywords : p-phenylsulfonyl-aniline; poly(p-phenylsulfonyl-aniline); electrical conductivity; polyaniline; conducting polymer.
