Abstract
AbstractPolyaniline/poly(vinyl acetate) (PAn/PVAc) copolymer was prepared in aqueous solution by the copolymerization of vinyl acetate and aniline using a mixture of KIO3 and (NH4)2S2O8 as an oxidant in the presence of the surfactants sodium dodecylbenzenesulfonate, poly(ethylene glycol), and hydroxypropylcellulose. The PAn/PVAc copolymers were characterized in terms of their conductivity, morphology, and structure. The results indicated that the morphology and conductivity of the products were dependent on the type of surfactant used (anionic or nonionic). Furthermore, it was found that adding vinyl acetate monomer to the stirred aqueous solution containing oxidant, surfactant, and aniline monomer had a great effect on the morphology and increased the amount of the product. The structures of the products were determined by FTIR spectroscopy. J. VINYL ADDIT. TECHNOL., 13:229–233, 2007. © 2007 Society of Plastics Engineers
