A novel crystalline polymer (DE-BP Polymer) was synthesized by reacting an epoxy resin having a diphenylene
ether structure (DGDE) with 4,4’-dihydroxybiphenyl. Then, the properties of DE-BP Polymer were
compared with those of the polymer from DGDE and 4,4’-dihydroxydiphenylether( DE-DE Polymer). The
melting point of DE-BP Polymer in differential scanning calorimetry was 245.6 ℃ , which was 59.8 ℃ higher
than that of DE-DE Polymer, and the glass transition temperature in dynamic mechanical analysis was
120.2℃ , which was 26.5℃ higher than that of DE-DE Polymer. In addition, the thermal conductivity of DEBP
Polymer was 0.33 W / m·K, which was higher than that of DE-DE Polymer.
