Abstract
A new epoxy resin containing trisbenzyl isocyanurate moiety (TGBIC) was synthesized by the reaction of epichlorohydrin and a phenolic compound which obtained from cyanuric acid, 2, 6-dimethylphenol, and paraformaldehyde. In order to evaluate the effect of trisbenzyl isocyanurate moiety on the thermal properties, triglycidyl isocyanurate (TGIC) and diglycidyl ether of 3, 3', 5, 5'-tetramethylbisphenol-F (DGTBF) were used as references. The cured polymer of TGBIC with phenol novolac showed glass transition temperature of 189.2 °C in DMA measurement which was 47.6 °C higher than that of the DGTBF polymer, and gave initial thermal decomposition temperature of 332.1 °C which was 71.9 °C higher than that of the TGIC polymer. These results might be attributed to the aromatic structure and the rigid isocyanurate moiety in TGBIC.
