Abstract
A wide‐band reflective polarizer from glassy siloxane cyclic side‐chain liquid crystals with stable optical properties was developed. The pitch gradient that formed was first stored by rapid cooling, which, by preventing the crystallization of glassy materials, was a very easy way of keeping the molecular arrangement. Then, the polymer network that formed through UV‐initiated chain crosslinking of the photopolymerizable monomers in the reflective polarizer further stabilized the cholesteric structure stored by the former rapid cooling. © 2007 Wiley Periodicals, Inc.
