Abstract

We report here on the contrasts observed between a terpolymer with ordered chemical sequences and its chemically disordered isomer. The chemically ordered terpolymer and its disordered analogue were both liquid crystal polymers synthesized in our laboratory. Optical microscopy reveals that the disordered isomer exhibits a biphasic region spanning 120 degree C where both birefringent and isotropic fluid coexist. In great contrast, the chemically ordered terpolymer exhibits a distinct transition from the liquid crystalline to the isotropic phase over the very narrow range of 5 degree C.
