Liquid crystalline thermosetting epoxy oligomer DD-A was synthesized with Diglycidyl ether of 4,4'-dihydroxy-α-methylstilbene (DGE-DHMS) and aniline in a ratio of 2:1 and cured with a catalytic curing agent, 1-Methyl Imidazole. The gelation times and vitrification times were measured to create Time-Temperature-Transition Diagrams with liquid crystalline phase changes. It was found that the gelation and vitrification times were decreased as the concentration of curing agent increased, and the vitrification curve showing a typical S-shape was confirmed.
