dc.description.abstractThe synthesis of an aromatic ester based liquid crystalline epoxy resin
(LCE) with a substituent in the mesogenic central group is described. Chlorine and
methyl groups were introduced as substituents. The curing behaviors of three epoxy
resins were investigated using diaminodiphenyl ester as the curing agent. The curing
rate and heat of curing of LCE were measured with dynamic and isothermal DSC.
The chlorine substituent accelerated the curing of LCE, while the methyl substituent
decelerated the curing of LCE. The heat of curing of substituted LCE was diminished
compared to LCE with no substituent. Glass transition temperature and elastic modulus
of LCE decreased with increasing the size of the substituent. Three liquid crystalline
epoxy resins based on aromatic ester mesogenic groups formed a liquid crystalline
phase after curing, and the liquid crystalline phase was stable up to the decomposition
temperature.
