The synthesis of three cholesteric divinyl ethers is described. One of them is suitable for forming polymeric networks by isothermal cationic photopolymerization. Such networks exhibit temperature-stable reflection bands. By mixing with nematic divinyl ethers before polymerization, the reflection wavelength of such networks can be chosen by the relative amount of both types of divinyl ethers.
