ABSTRACT:
This invention provides novel liquid crystalline polymers which comprise, in the repeat units of their main chains, residues of suitable dichroic dyes. The polymers yield polarizer films with superior polarizing efficiency, transmittance, dichroic ratio, and thermal and humidity stability. The invention further discloses suitable processes to prepare such polymers and polarizer films therefrom.
