Synthesis, characterization and electrical properties of poly(p-phenylsulfonyl-aniline)

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