✦ Synopsis

Main-chain liquid-crystalline polymers containing triad aromatic ester mesogenic blocks together with flexible ion-complexing oligo-oxyethylene blocks have been synthesized. A range of polyoxyethylene precursor polymers was employed with two different triad units to produce mechanically robust polymers exhibiting liquid-crystalline behaviour in the general range loO-200°C. Films were formed consisting of complexes with lithium trifluoromethane sulphonate. Useful ionic conductivities were obtained.
