Synthesis and characterization of copolymer of aniline/vinyl acetate by emulsion polymerization pathway in aqueous and aqueous/non-aqueous media

Polyaniline/Poly(vinyl acetate) (PAn/PVAc) copolymer was prepared in the aqueous/non-aqueous media by using mixture of KIO3 and (NH4)2S2O8 as an oxidant in the presence of various stabilizers such as sodium dodecylbenzenesulfonate, poly(vinyl alcohol) and hydroxypropylcellulose. The products were characterized in terms of conductivity, morphology, yield, particle size and chemical structure. The results indicate that the surface morphology, yield, particle size and conductivity of product are dependent on the type of surfactant. Also, the chemical structure of obtained product was determined by FTIR spectroscopy.
