Abstract: Disclosed is a novel process for effecting an ether interchange reaction by heating together in the presence of a basic catalyst, a nitroaromatic ether or thioether and an organic compound containing at least one hydroxyl or mercapto group. The novelty resides particularly in carrying out the interchange in an inert solvent while sparging the heated reactants thereby to remove at least a portion of solvent along with an evolving alcohol or thiol.The process is particularly adapted to the capping of organic polyols with nitroaromatic ether groups. The capped products are useful as intermediates for the preparation of high molecular weight polyamines which in turn find utility in various polymer applications.

Abstract: Liquid crystalline side-chain polyesters prepared by polycondensing a dicarboxylic acid or a derivative thereof with a diol of a certain general formula. Of such diols the essence is that they have a delocalized .pi. electron system to which both an electron donor group and an electron acceptor group are coupled directly (D.pi.A-system). Because of the structure of the diol to which the D.pi.A-system is linked the polyesters exhibit excellent Tg and Tc values. The polyesters are to be used in optical waveguides or for optical data storage.
