Infrared dichroism of liquid crystalline terephthalate and biphenyldicarboxylate polyesters

  • Published:
Polymer Bulletin Aims and scope Submit manuscript

Summary

Polarised infrared spectroscopy has been used in the structural elucidation of the liquid crystalline polyesters, poly(2-phenyl-1,4-phenylene terephthalate), poly(2-phenyl-1,4-phenylene-4,4′-biphenyldicarboxylate) and the copolyester containing both terephthalate and biphenyldicarboxylate units. Order parameters have been calculated and the dichroic behaviour of the vibrational modes used to give valuable insight into the polymer chain structure.
