An epoxy resin having a m-terphenyl structure( DGMTP) was synthesized, followed by evaluating the physical
properties of the cured polymer with phenol novolac. The glass transition temperature was 160℃ , which
was 33℃ higher than that of bisphenol A type epoxy resin (DGBPA), and 4 ℃ higher than that of biphenyl
type epoxy resin (DGTBP). In addition, the char yield at 700℃ was 29.2 wt%, which was significantly higher
than 15.6 wt% of DGBPA, and the 10 wt% weight loss temperature was 404℃ . These results indicate higher
thermal stability of the DGMTP cured polymer based on a m-terphenyl structure.
