Abstract

A novel naphthalene based epoxy resin having an azomethine structure (GNMB) was synthesized, and the properties of the cured polymer using phenol novolac as a hardener were compared with those of the phenyl ring based epoxy resin having an azomethine structure (GPMB) and the bisphenol A type epoxy resin (DGBPA). The glass transition temperature of the GNMB polymer was 172℃, which was 11℃ and 45℃ higher than those of the GPMB, and DGBPA polymers, respectively. In addition, the thermal conductivity of the GNMB polymer was 0.28 W/m・K, which was 1.4 times higher than that of the DGBPA polymer.
