An epoxy resin having a triphenylene ether structure( BGPBZ) was synthesized and the physical properties
of a cured polymer obtained by curing with 4,4’-dihydroxydiphenyl ether( DHDE) were evaluated. BGPBZ
gave a crystalline cured polymer with a melting point of 203.4℃ , which was 17.8℃ higher than that of epoxy
resin having a diphenylene ether structure( DGDPE). The thermal expansion coefficient of the crystalline
cured polymer is 4.4×10-5 ℃-1, which is 30% lower than that of the amorphous cured polymer. In addition, the
thermal conductivity is 0.32 W/m・K, which is about 1.5 times that of the amorphous cured polymer.
