title: [Spectroscopic ellipsometry characteristics and the optical properties of liquid crystalline copolyesters].
abstract: The optical properties of two thermotropic liquid crystalline copolyesters were characterized by spectroscopic ellipsometry and UV-visible spectroscopy. The differences in the refractive index variation and chromatic dispersion have been revealed and discussed in terms of differences in the vibrating transition of excited electrons and the molecular structures of the polymers.
