Structural isomerism in Polycondensates. Part IV. Synthesis and characterization of liquid crystalline poly(azomethines) and low molecular weight model compounds
With the aim to investigate the influence of structuralisomerism on the mesomorphic thermal stability in main chain thermotropic polycondensates, a series of poly(azomethines) and low molecular weight models have been prepared. The model compounds exhibit smectic and/or nematic mesophases whose stabilites are very sensitive to structural modifications. On the basis of the above results, monomers 2
