Synthesis of a bifunctional epoxy monomer containing anthracene moiety andproperties of its cured polymer with phenol novolac

A new type of epoxy resin containing anthracene moiety in the backbone was synthesized and was confirmed by elemental analysis, infrared spectroscopy, and H-1 nuclear magnetic resonance spectroscopy. Thermal properties of its cured polymer with phenol novolac were examined by thermomechanical, dynam ic mechanical, and thermogravimetric analyses. The cured polymer with pheno l novolac showed higher glass transition temperature (T-g), lower thermal e xpansion, lower moisture absorption, and higher anaerobic char yield at 700 degrees C than a cured polymer having a phenylene group in place of anthra cene moiety.
