Dispersing liquid crystal droplets in a rigid polymer matrix results in an electrically controllable light scattering medium. A polymer with high glass transition temperature phase‐separated with a low molecular weight liquid‐crystalline material is a good binder for polymer dispersed liquid crystals (PDLC). Main‐chain liquid‐crystalline epoxies were synthesized for the phase separation with low molecular weight nematic liquid crystals E7 (mixture of 4‐alkyl‐4′‐cyanobiphenyls) and studied for their mesomorphic properties and response to an applied electrical field.
