The paper reports on the enhancement of electrical conductivity of a liquid crystalline aromatic polymer following its alignment in a magnetic field. The interaction of external fields with 'polymeric' liquid crystals offers the possibility of freezing the molecular organization which these fields induce, and therefore a way to control the anisotropy of physical properties in solid polymers. One material under investigation is a semi-flexible polyester that becomes liquid crystalline near 150 degree C. The polymer's carbon-13 NMR spectrum is shown. It is concluded that some rearrangement occurs in the melt polymerization and the chain microstructure is more complicated than that suggested by the chemical structure.
