This invention provides novel liquid crystalline polymers which, when blended with a suitable dye at a suitable high temperature and extruded, yields polarizer films with superior thermal and hygroscopic stability and polarizing efficiency. The invention further provides a process to prepare such polarizer films.

Polarizer films with high thermal and hygroscopic stability

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

This invention provides all organic high extinction polarizers based on blends of novel liquid crystalline polymers and suitable dichroic dyes. The invention further provides a process to prepare such polarizer films.

High extinction polarizer films comprising liquid crystal polymeric

There is disclosed and claim a multi-layer polymeric optical element including at least two poled film members exhibiting nonlinear optical susceptibility. The films may be poled in an ordinary atmosphere under relatively mild conditions, or corona poled at high voltage. The elements are particularly useful for periodic or quasi-random optical applications such as parametric amplification of light or frequency doubling.
