This invention provides novel liquid crystalline polymers which, when mixed with a suitable dye and extruded, yields polarizer films with superior polarizing efficiency, transmittance, dichroic ratio, and thermal and humidity stability. The invention further provides a process to prepare such polymers and polarizer films therefrom.

Polarizer films comprising wholly aromatic liquid crystalline polymers

In one embodiment this invention provides novel side chain copolymers which exhibit nonlinear optical response, and which have utility as a transparent optical component in all-optical and electrooptical light switch and light modulator devices. The invention side chain copolymer is illustrated by the following structure: ##STR1##
