Title: Synthesis and Curing of Liquid Crystalline Epoxy Resin with Low Melting Point
Abstract: A liquid crystalline epoxy resin p-methylphenylene di{4-(2,3-epoxypropoxy) ethoxy benzoate}(MPEPEB),which had a low melting point,was synthesized,and the structure and phase behavior of the synthesized product were characterized by means of IR,EA,1H-NMR,DSC and hot stage POM.The results showed MPEPEB showed a nematic mesophase between 78.7 ℃ and 133.9 ℃,and the mesophase maintained till -50 ℃ in cooling.The curing of MPEPEB/DDM was investigated.There were two exothermic peaks in dynamic DSC curve and two Ea in the isothermal curing which may be correlated with the appearance of mesophase.
