Abstract: Conductive thermosetting epoxy resins are produced by mixing a metallic salt or oxide with an inorganic acid to form a metallic ion solution. An alcohol is added to effect a secondary dehydration and form a complex ion polymer with double bonds and p electrons. The mixture is neutralized to produce a high molecular weight polymer of low electronic impedance. This polymer is then copolymerized with an epoxy resin.
