ABSTRACT:
This invention discloses laminates comprising a liquid crystal polymer film inside and non-adherent, non-liquid crystalline polymer film on the outside, prepared by a process of coextrusion. Delamination of the outside layers yields a liquid crystal polymer film of superior surface quality. The invention is particularly suitable for preparing liquid crystal polymer-based polarizers with improved surface quality.
