Structure-property relationship of highly ??-conjugated schiff-base moiety in liquid crystal diepoxide polymerization and mesophases stabilization

A study of the structure-property relationship of the highly ??-conjugated Schiff-base moiety in polymerization of a liquid crystal (LC) diepoxide oligomer (PBMBA) and mesophases stabilization has been investigated. We first proposed two exothermic peaks

Using the liquid crystalline epoxy resin thermoset aromatic diamine

PROBLEM TO BE SOLVED: To provide an aromatic diamine that gives a heat-cured product useful as an electric insulation material for radiating the heat generated from a semiconductor element and the like, and a liquid crystalline epoxy resin heat-cured product prepared therewith.SOLUTION: This invention relates to an aromatic diamine represented by formula (1), and a heat-cured product of the diamine and a liquid crystalline bisepoxide represented by formula (2) (where R-Rindependently represent a hydrogen atom, a C1-C6 alkyl group or a C1-C6 alkoxy group, m is an integer of 2-14, and Xis a divalent aromatic group).SELECTED DRAWING: None

ELECTRONIC ABSORPTION SPECTRA OF AROMATIC SCHIFF BASES. PART II. TEREPHTHALDEHYDE DERIVATIVES

The effect of para substituents in the aniline moiety of terephthalidene-di(p-R-anilines) on their UV-VIS spectra has been studied.A linear relationship has been found between position of long-wavelength absorption bands of terephthalidene-dianilines with
