Abstract
Three new series of main chain liquid crystalline polyesters consisting of arómatic-type Schiff base mesogenic units and polymethylene spacers were synthesized and their thermal transitions and liquid crystalline properties were studied. All three series exhibited an even-odd effect in melting and isotropization temperatures. They formed nematic mesophases in melts as judged by their optical textures observed through a polarizing microscope and by X-ray diffraction analysis.
