Cobalt acrylate (CoA 2 ) has been treated with bisphenol‐A and epichlorohydrin to modify epoxy resins. It was cured with p ‐acetylbenzilidene triphenyl arsonium ylide. The properties such as epoxide equivalent weight (equiv/100 g), molecular weight, hydrolyzable chlorine content increases whereas hydroxyl content, refractive index decreases in the presence of CoA 2 . The cured epoxy resins shows improve electrical conductivity due to the incorporation of CoA 2 with epoxy resins. The influence of complex formation of CoA 2 with either linkage of epoxy resins were investigated by spectroscopy. The decrease in T g from differential scanning calorimetry support the improve in flexibility. The dispersion of cobalt in epoxy resins matrix was confirmed by scanning electron microscope. © 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2009
