Advanced ordered material based on liquid crystalline azomethine diepoxide

Abstract : A liquid crystalline thermoset (LCT) was prepared by curing a mesogenic azomethine diepoxide, N,N'-(1,4-phenylenedimethylidyne)-di-4-(2,3-epoxypropoxy) aniline (AZ-2), with 4,4'-methylene-bis-(3-chloro-2,6-diethyla niline) (MCDEA). The cross-linking reaction, the phase transition and the thermal properties of the LCT have been investigated by differential scanning calorimetry (DSC). The polarized optical microscopy (POM) reveals the formation of an ordered E smectic structure during curing. This structure has been confirmed by wide-angle-X-ray scattering (WAXS) study.
