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.
