Abstract

Cobalt acrylate (CoA2) 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 CoA2. The cured epoxy resins shows improve electrical conductivity due to the incorporation of CoA2 with epoxy resins. The influence of complex formation of CoA2 with either linkage of epoxy resins were investigated by spectroscopy. The decrease in Tg 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
