Abstract
A liquid crystalline thermosetting epoxy 4,4'-diglycidyloxy-${\alpha}$-methylstilbene (DOMS) was synthesized using sulfanilamide as the curing agent. To heat cure the epoxy, filler contents of 0.5-5 wt% zirconia were used. Thermogravimetric analysis was performed, and the activation energy was calculated using the Kissinger and Flynn-Wall methods. The activation energy was proportional to the amount of zirconia used. As the activation energies needed for 1% and 10% decomposition were similar, the thermal decomposition was predicted to have the same mechanism.
